[jira] [Commented] (DRILL-1683) malformed config file parse exception silently swallowed - drill fails to start

["Sean Hsuan-Yi Chu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-1683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14222241#comment-14222241 ] 

Sean Hsuan-Yi Chu commented on DRILL-1683:
------------------------------------------

The file "/tmp/drill/sys.storage_plugins/hbase.sys.drill" is the storage plugin which one can modify in the Web-UI. (In the case of embedded mode, http://localhost:8047/storage/hbase).

Maybe the error in this issue is specific to Eclipse? Can you check again if it would still go wrong?

> If I remove that file, I am then able to start the embedded drillbit. I note that after I do so, the file has been recreated with different contents. If the problem is because the configuration for this storage plugin has changed, then this seems like it will cause many mysterious startup failures after upgrading.
