Method Detail

closeIndices

public void closeIndices(CloseIndexClusterStateUpdateRequest request,
                         ActionListener<CloseIndexResponse> listener)

Closes one or more indices. Closing indices is a 3 steps process: it first adds a write block to every indices to close, then waits for the operations on shards to be terminated and finally closes the indices by moving their state to CLOSE.

openIndex

public void openIndex(OpenIndexClusterStateUpdateRequest request,
                      ActionListener<OpenIndexClusterStateUpdateResponse> listener)

createIndexClosingBlock

public static ClusterBlock createIndexClosingBlock()

Returns:

Generates a ClusterBlock that blocks read and write operations on soon-to-be-closed indices. The cluster block is generated with the id value equals to INDEX_CLOSED_BLOCK_ID and a unique UUID.

isIndexVerifiedBeforeClosed

public static boolean isIndexVerifiedBeforeClosed(IndexMetaData indexMetaData)
