Method Summary

Modifier and Type	Method and Description
org.apache.hadoop.fs.Path	dataExportRootDir() Access to the dataExportRootDir should only be done via this method since the creation of the directory is delayed until we figure out if we want to write something or not.
org.apache.hadoop.fs.Path	metadataExportRootDir() Access to the metadataExportRootDir should only be done via this method since the creation of the directory is delayed until we figure out if we want to write something or not.

Method Detail

metadataExportRootDir

public org.apache.hadoop.fs.Path metadataExportRootDir()
                                                throws SemanticException

Access to the metadataExportRootDir should only be done via this method since the creation of the directory is delayed until we figure out if we want to write something or not. This is specifically important to prevent empty non-native directories being created in repl dump.

Throws:

SemanticException

dataExportRootDir

public org.apache.hadoop.fs.Path dataExportRootDir()
                                            throws SemanticException

Access to the dataExportRootDir should only be done via this method since the creation of the directory is delayed until we figure out if we want to write something or not. This is specifically important to prevent empty non-native directories being created in repl dump.
