-------------------------------------
Summary: Misc improvement to Acid module
Key: HIVE-12620
URL: https://issues.apache.org/jira/browse/HIVE-12620
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 1.3.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
# DbLockManger.unlock() - if this fails (due to no such lock in turn due to
timeout) the lock is not removed from DbLockManger internal tracking
# Add logic to DBLockManager to detect if there is attempt to interleave
transactions or locks from different statements for read-only auto commit mode
# TxnHandler.checkLock() can use 1 connection instead of 2
# TxnHandler.timeOutLocks() - refactor so that it can log which locks were
expired (simplifies debugging)
# TxnHandler#getTxnIdFromLockId() - include lock id if it's not found
# TxnHandler#checkRetryable() - log exception it saw
