------------------------------------------
Summary: TestDbTxnManager generates a huge hive.log
Key: HIVE-16109
URL: https://issues.apache.org/jira/browse/HIVE-16109
Project: Hive
Issue Type: Bug
Reporter: Vihang Karajgaonkar
Assignee: Vihang Karajgaonkar
Pre-commit jobs are failing currently due to out of disk space. The issue is
happening due to huge size of hive.log when TestDbTxnManager test fails or
times-out. When this test fails or times-out Ptest tries to persist these logs
for debugging. Since this test has been timing out frequently, this accumulates
a lot of these log files and eventually Ptest server runs of disk space. Each
run of TestDbTxnManager is generating ~30 GB of hive.log. I tried to run it
locally and it quickly reached 7 GB until I had to cancel it.
The issue seems to be coming from this code block in TxnHandler.java
{noformat}
if(LOG.isDebugEnabled()) {
LOG.debug("Locks to check(full): ");
for(LockInfo info : locks) {
LOG.debug(" " + info);
}
}
{noformat}
We should either change it trace or change the log mode of this test to INFO so
that it generates smaller log files.
