Subject [jira] [Commented] (HBASE-17474) Reduce frequency of NoSuchMethodException when calling setStoragePolicy()
Date Tue, 17 Jan 2017 05:46:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15825486#comment-15825486
] 

Yu Li commented on HBASE-17474:
-------------------------------

Maybe simply add an if clause to exempt LocalFileSystem could fix this, like below:
{code}
      if (!(this.fs instanceof LocalFileSystem)) {
        LOG.warn("Failed to set storage policy of [" + storeDir + "] to [" + policyName +
"]", e);
      }
{code}

Sounds good [~tedyu]? If so, will make a straight-forward patch. Thanks.

> We should reduce the frequency of the above log since it clutters test output.
