[jira] [Comment Edited] (SPARK-23831) Add org.apache.derby to IsolatedClientLoader

    [ https://issues.apache.org/jira/browse/SPARK-23831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16685950#comment-16685950 ]

-----------------------------------------------------------------

Because it caused a problem that Hive enabled session is restarted. I talked with [~yumwang] and looks it does not fix an actual usecase but the fix breaks one actual usecase. The fix and root causes were not perfectly understood so I rather reverted.

Is there an actual case broken or fixed by this PR? If so, I don't object to restore this as I explained in the PR.
