> Key: HIVE-12389
> URL: https://issues.apache.org/jira/browse/HIVE-12389
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Transactions
> Affects Versions: 1.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Attachments: HIVE-12389.2.patch, HIVE-12389.3.patch, HIVE-12389.patch

>
> in extreme situations, due to misconfigurations, it may be possible to have
> 100Ks or even 1Ms of aborted txns.
> This causes delete from TXNS where txn_id in (...) to have a huge IN clause
> and DB chokes.
> Should use something like TxnHandler.TIMED_OUT_TXN_ABORT_BATCH_SIZE to break
> up delete into multiple queries. (Incidentally the batch size should likely
> be 1000, not 100, maybe even configurable).
> On MySQL for example, it can cause query to fail with
> bq. Packet for query is too large (9288598 > 1048576). You can change this
> value on the server by setting the max_allowed_packet' variable.
