getQueryWriteInfo

LocationService.WriteInfo getQueryWriteInfo(com.facebook.presto.hive.LocationHandle locationHandle)

targetPath and writePath will be root directory of all partition and table paths that may be returned by getTableWriteInfo(LocationHandle) and getPartitionWriteInfo(LocationHandle, Optional, String) method.

getTableWriteInfo

LocationService.WriteInfo getTableWriteInfo(com.facebook.presto.hive.LocationHandle locationHandle)

getPartitionWriteInfo

LocationService.WriteInfo getPartitionWriteInfo(com.facebook.presto.hive.LocationHandle locationHandle,
