ElasticSearchServer

public ElasticSearchServer(Map<String,String> configuration)

Method Detail

start

public void start()

stop

public void stop()

getClient

public org.elasticsearch.client.Client getClient()

maxOpenFiles

protected int maxOpenFiles(File testDir)

deleteRecursively

protected boolean deleteRecursively(File root)

deleteRecursively

protected boolean deleteRecursively(File root,
                        boolean deleteRoot)

Delete the supplied File - for directories, recursively delete any nested directories or files as well.

Parameters:

root - the root File to delete

deleteRoot - whether or not to delete the root itself or just the content of the root.

Returns:

true if the File was deleted, otherwise false

getHealthStatus

protected org.elasticsearch.action.admin.cluster.health.ClusterHealthStatus getHealthStatus()

checkServerStatus

protected void checkServerStatus()

Wait for the ES server to reach at least YELLOW state. If YELLOW or GREEN is not reached, we throw a runtime exception in order to abort the boot process. This code would be a lot simpler if the ES client would not throw a MasterNotFoundException, but it sometimes does this if a call is made while the server's are still negotiating who will be master.

getValue

protected static String getValue(Map<String,String> map,
              String key)

setRecoveryWait

public void setRecoveryWait(String recoveryWait)
