Subject: [jira] [Updated] (HIVE-8203) ACID operations result in NPE when run

Alan Gates updated HIVE-8203:
-----------------------------
    Attachment: HIVE-8203.patch

This patch moves initialization of the transaction manager from runInternal to compile.  This way paths that call compile first (such as HS2) will not NPE.  Also it moves acquisition of the valid transaction list until after a transaction has been opened and locks are acquired.  Finally, I added logic in construction of the valid transaction list to remove the current user's transaction from the list of open transactions so that operations would see rows created inside their own transaction.
