[jira] [Commented] (ACCUMULO-1470) logger.dir.walog description
should say that the WAL is stored on the "HDFS filesystem"
[ https://issues.apache.org/jira/browse/ACCUMULO-1470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13669671#comment-13669671 ]
Aaron Glahe commented on ACCUMULO-1470:
---------------------------------------
This is based on, from what I can tell, the WAL being written into the "/accumulo" on the DFS. However, what is weird, is that even though I had the default (walogs), the DIR that was created was "wal."
In looking over the code, the LOGGER_DIR property does have the default set to "walogs", but when looking at org.apache.accumulo.core.Constants:
/**
* @param conf
* @return The write-ahead log directory.
*/
public static String getWalDirectory(final AccumuloConfiguration conf) {
return getBaseDir(conf) + "/wal";
}
which is where I BELIEVE (not sure) that being used instead of the LOGGER_DIR.
