Constructor Detail

PackageManager

public PackageManager(HttpSolrClient solrClient,
                      String solrBaseUrl,
                      String zkHost)

Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

fetchInstalledPackageInstances

public List<SolrPackageInstance> fetchInstalledPackageInstances()
                                                         throws SolrException

Throws:

SolrException

getPackagesDeployed

public Map<String,SolrPackageInstance> getPackagesDeployed(String collection)

getPackagesDeployedAsClusterLevelPlugins

public Map<String,SolrPackageInstance> getPackagesDeployedAsClusterLevelPlugins()

Get a list of packages that have their plugins deployed as cluster level plugins. The returned packages also contain the "pluginMeta" from "clusterprops.json" as custom data.

verify

public boolean verify(SolrPackageInstance pkg,
                      List<String> collections,
                      boolean shouldDeployClusterPlugins,
                      String[] overrides)

Given a package and list of collections, verify if the package is installed in those collections. It uses the verify command of every plugin in the package (if defined).

Parameters:

overrides - are needed only when shouldDeployClusterPlugins is true, since collection level plugins will get their overrides from ZK (collection params API)

getPackageInstance

public SolrPackageInstance getPackageInstance(String packageName,
                                              String version)

Get the installed instance of a specific version of a package. If version is null, PackageUtils.LATEST or PackagePluginHolder.LATEST, then it returns the highest version available in the system for the package.

deploy

public void deploy(String packageName,
                   String version,
                   String[] collections,
                   boolean shouldInstallClusterPlugins,
                   String[] parameters,
                   boolean isUpdate,
                   boolean noprompt)
            throws SolrException

Deploys a version of a package to a list of collections.

Parameters:

version - If null, the most recent version is deployed. EXPERT FEATURE: If version is PackageUtils.LATEST, this collection will be auto updated whenever a newer version of this package is installed.

isUpdate - Is this a fresh deployment or is it an update (i.e. there is already a version of this package deployed on this collection)

noprompt - If true, don't prompt before executing setup commands.

Throws:

SolrException

undeploy

public void undeploy(String packageName,
                     String[] collections,
                     boolean shouldUndeployClusterPlugins)
              throws SolrException

Undeploys a package from given collections.

Throws:

SolrException

getDeployedCollections

public Map<String,String> getDeployedCollections(String packageName)

Given a package, return a map of collections where this package is installed to the installed version (which can be PackagePluginHolder.LATEST)
