  • Method Details

    • resolveTranslog

      public  resolveTranslog()

    • resolveIndex

      public  resolveIndex()

    • getDataPath

      public  getDataPath()

    • exists

      public boolean exists()

    • getShardId

      public ShardId getShardId()

    • getShardStatePath

      public  getShardStatePath()

    • getRootDataPath

      public  getRootDataPath()
      Returns the data-path root for this shard. The root is a parent of getDataPath() without the index name and the shard ID.

    • getRootStatePath

      public  getRootStatePath()
      Returns the state-path root for this shard. The root is a parent of getRootStatePath() ()} without the index name and the shard ID.

    • isCustomDataPath

      public boolean isCustomDataPath()
      Returns true iff the data location is a custom data location and therefore outside of the nodes configured data paths.

    • loadShardPath

      public static ShardPath loadShardPath​(org.apache.logging.log4j.Logger logger, NodeEnvironment env, ShardId shardId,  customDataPath) throws
      This method walks through the nodes shard paths to find the data and state path for the given shard. If multiple directories with a valid shard state exist the one with the highest version will be used. Note: this method resolves custom data locations for the shard if such a custom data path is provided.
      Throws:

    • loadShardPath

      public static ShardPath loadShardPath​(org.apache.logging.log4j.Logger logger, ShardId shardId,  customDataPath, [] availableShardPaths, int nodeLockId,  sharedDataPath) throws
      This method walks through the nodes shard paths to find the data and state path for the given shard. If multiple directories with a valid shard state exist the one with the highest version will be used. Note: this method resolves custom data locations for the shard.
      Throws:

    • deleteLeftoverShardDirectory

      public static void deleteLeftoverShardDirectory​(org.apache.logging.log4j.Logger logger, NodeEnvironment env, ShardLock lock, IndexSettings indexSettings, <[]> listener) throws
      This method tries to delete left-over shards where the index name has been reused but the UUID is different to allow the new shard to be allocated.
      Throws:

    • selectNewPathForShard
