-------------------------------------
Summary: ACID: drop table doesn't acquire any locks
Key: HIVE-10241
URL: https://issues.apache.org/jira/browse/HIVE-10241
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 1.0.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
with Hive configured to use DbTxnManager, in DbTxnManager.acquireLocks() both
plan.getInputs() and plan.getOutputs() are empty when "drop table foo" is
executed and thus no locks are acquired. We should be acquiring X locks to
make sure any readers of this table don't get data wiped out while read is in
progress.
