(was: 3.1)
> SQL query may forget to finish implicit TX.
> -------------------------------------------
>
> Key: IGNITE-18326
> URL: https://issues.apache.org/jira/browse/IGNITE-18326
> Project: Ignite
> Issue Type: Bug
> Reporter: Andrey Mashenkov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.2
>
>
> Scenario
> * Start grid of [CGM, MetaStorage, DataNode] nodes.
> * Stop DataNode.
> * Run sql query, and wait on future for timeout.
> * Observe: Query can't be started due to DataNode with the partition is
> absent, and
> Future throws CancelledException.
> There is no way to get cursor closed because of future failure. Implicit
> transaction object can't be accessed.
> * Start DataNode back.
> * Run the same query again
> * Observe: Query failed because it can't lock the entry due to previous Tx
> wasn't committed or rolled back.
> Most likely, noone read from the cursor or we forget to close it when session
> was closed.
> ---- *UPDATED* ---
> After some investigations i found that tx commited and rolled back correctly,
> the only problem i can found for now is mentioned above "it can't lock the
> entry due to previous Tx". Check [1], test called :
> *testImplicitTransaction0* it makes all described above, by Andrey, sometimes
> it passed but frequently we can obtain :
