[jira] [Commented] (HIVE-22580) Flakyness in TestDbTxnManager2
[ https://issues.apache.org/jira/browse/HIVE-22580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16987840#comment-16987840 ]
Peter Vary commented on HIVE-22580:
-----------------------------------
My theory is that the previous test ends, and the heartbeating thread is interrupted inside of the derby call. MetaStoreDirectSql.ensureDbInit() catches the InterruptedException (this happens only with EmbeddedMetaStore), and never rethrows it. So the heartbeater never interrupted, and RetryingMetaStoreClient retries the heartbeat. This recreates/reinitializes the txnDb, see:
{code}
2019-12-03T20:18:49,221 INFO [Heartbeater-1] txn.TxnHandler: Hacking in canned values for transaction manager
{code}
This log line is printed just before {code}TxnDbUtil.prepDb(conf);{code} is executed, so the heartbeater thread starts to recreate the txnDb related tables.
The main thread finishes the previous test case, and runs setup for the next test. This also drops, and starts the txnDb related tables. But sees that the first table is already there and so decided that the tables are already there:
{code}
2019-12-03T20:18:49,235 INFO [main] txn.TxnDbUtil: Txn tables already exist, returning
{code}
The problem is that not all of the tables are there. So when it wants to read the NEXT_TXN_ID it fails, since the first thread (heartbeater) is not there.
So the issue is twofold:
* Need a fix how MetaStoreDirectSql.ensureDbInit() handles InterruptedException - this is kinda risky, might worth another jira to understand the sideeffects of this.
* Need to synchronize TxnDbUtil.prepDb(), so no concurrent table creation happens
