public HdfsDirectoryFactory()

Deprecated.

Method Detail

close

public void close()
           throws IOException

Deprecated.

Description copied from class: DirectoryFactory

Close the this and all of the Directories it contains.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface SolrMetricProducer

Overrides:

close in class CachingDirectoryFactory

Throws:

IOException - If there is a low-level I/O error.

init

public void init(NamedList args)

Deprecated.

Specified by:

init in interface NamedListInitializedPlugin

Overrides:

init in class CachingDirectoryFactory

createLockFactory

protected org.apache.lucene.store.LockFactory createLockFactory(String rawLockType)
                                                         throws IOException

Deprecated.

Description copied from class: DirectoryFactory

Creates a new LockFactory for a given path.

Specified by:

createLockFactory in class DirectoryFactory

Parameters:

rawLockType - A string value as passed in config. Every factory should at least support 'none' to disable locking.

Throws:

IOException - If there is a low-level I/O error.

create

protected org.apache.lucene.store.Directory create(String path,
                                                   org.apache.lucene.store.LockFactory lockFactory,
                                                   DirectoryFactory.DirContext dirContext)
                                            throws IOException

Deprecated.

Description copied from class: DirectoryFactory

Creates a new Directory for a given path.

Specified by:

create in class DirectoryFactory

Throws:

IOException - If there is a low-level I/O error.

exists

public boolean exists(String path)

Deprecated.

Description copied from class: DirectoryFactory

Returns true if a Directory exists for a given path in the underlying (stable) storage and contains at least one file. Note that the existence of a Directory Object as returned by a previous call to the DirectoryFactory.get(java.lang.String, org.apache.solr.core.DirectoryFactory.DirContext, java.lang.String) method (on the specified path) is not enough to cause this method to return true. Some prior user of that Directory must have written & synced at least one file to that Directory (and at least one file must still exist)

Overrides:

exists in class CachingDirectoryFactory

getConf

public org.apache.hadoop.conf.Configuration getConf(org.apache.hadoop.fs.Path path)

Deprecated.

removeDirectory

protected void removeDirectory(CachingDirectoryFactory.CacheValue cacheValue)

Deprecated.

Overrides:

removeDirectory in class CachingDirectoryFactory

isAbsolute

public boolean isAbsolute(String path)

Deprecated.

Overrides:

isAbsolute in class DirectoryFactory

Parameters:

path - the path to check

Returns:

true if absolute, as in not relative

isPersistent

public boolean isPersistent()

Deprecated.

Specified by:

isPersistent in class DirectoryFactory

Returns:

true if data is kept after close.

isSharedStorage

public boolean isSharedStorage()

Deprecated.

Overrides:

isSharedStorage in class DirectoryFactory

Returns:

true if storage is shared.

searchersReserveCommitPoints

public boolean searchersReserveCommitPoints()

Deprecated.

Description copied from class: DirectoryFactory

If your implementation can count on delete-on-last-close semantics or throws an exception when trying to remove a file in use, return false (eg NFS). Otherwise, return true. Defaults to returning false.

Overrides:

searchersReserveCommitPoints in class DirectoryFactory

Returns:

true if factory impl requires that Searcher's explicitly reserve commit points.

getDataHome

public String getDataHome(CoreDescriptor cd)
                   throws IOException

Deprecated.

Description copied from class: DirectoryFactory

Get the data home folder. If solr.data.home is set, that is used, else base on instanceDir

Overrides:

getDataHome in class DirectoryFactory

Parameters:

cd - core descriptor instance

Returns:

a String with absolute path to data direcotry

Throws:

IOException

size

public long size(org.apache.lucene.store.Directory directory)
          throws IOException

Deprecated.

Overrides:

size in class DirectoryFactory

Parameters:

directory - to calculate size of

Returns:

size in bytes

Throws:

IOException - on low level IO error

size

public long size(String path)
          throws IOException

Deprecated.

Overrides:

size in class DirectoryFactory

Parameters:

path - to calculate size of

Returns:

size in bytes

Throws:

IOException - on low level IO error

getConfDir

public String getConfDir()

Deprecated.

initializeMetrics

public void initializeMetrics(SolrMetricsContext parentContext,
                              String scope)

Deprecated.

Description copied from interface: SolrMetricProducer

Initialize metrics specific to this producer.

Specified by:

initializeMetrics in interface SolrMetricProducer

Parameters:

parentContext - parent metrics context. If this component has the same life-cycle as the parent it can simply use the parent context, otherwise it should obtain a child context using SolrMetricsContext.getChildContext(Object) passing this as the child.

scope - component scope

inform

public void inform(SolrCore core)

Deprecated.

Specified by:

inform in interface SolrCoreAware

cleanupOldIndexDirectories

public void cleanupOldIndexDirectories(String dataDir,
                                       String currentIndexDir,
                                       boolean afterReload)

Deprecated.

Overrides:

cleanupOldIndexDirectories in class DirectoryFactory

renameWithOverwrite

public void renameWithOverwrite(org.apache.lucene.store.Directory dir,
                                String fileName,

                 org.apache.lucene.store.IOContext ioContext)
          throws IOException

Deprecated.

Description copied from class: DirectoryFactory

Override for more efficient moves. Intended for use with replication - use carefully - some Directory wrappers will cache files for example.

Overrides:

move in class DirectoryFactory

Throws:

IOException - If there is a low-level I/O error.
