Eugene Koifman commented on HIVE-12504:
---------------------------------------
ensureValidTxn() is a misnomer. What it really does is produce a more
informative error msg.
It's not practical to call it from abortTxns() since you won't know which txn
id to call it on.
> TxnHandler.abortTxn() should check if already aborted to improve message

> improve error msg.
> Note: get a separate read_committed connection for this.
