getRootDataPath
```
public Path 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 Path 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(ESLogger logger,
                                      NodeEnvironment env,
                                      ShardId shardId,

                               throws IOException

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.

例外:: IOException

deleteLeftoverShardDirectory

public static void deleteLeftoverShardDirectory(ESLogger logger,
                                                NodeEnvironment env,

                                         throws IOException

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.

例外:: IOException
