Mirza Aliev commented on IGNITE-16478:
--------------------------------------
We analysed debug logs from TC in and came up with possible ways of
investigation:
* Why we got {{ETIMEDOUT<1010>: RPC exception:null}} Probably it entail further
majority death {{[ERAFTTIMEDOUT<10001>: Majority of the group dies: 1/2]}} and
stepping down of the leader.
* In log we could see that we have several {{can't apply,
status=Status[EPERM<1008>: Is not leader.]}} messages, which means that some
task weren't applied to leaders log. Need to figure out what task weren't
applied and check if we lost them completely.
* In logs we can see {{called hasNext = false, cur = null}} which was logged
after {{internalBatchCounter = 0 clo.command().getCounter() = 1}}, hasNext =
false is not expected as far as new leader was supposed to return true for our
scan command. That means that we've got {{isValid}} equal false for internal
iterator {{RocksIterator}} of RocksDB. (see
{{org.apache.ignite.internal.rocksdb.RocksIteratorAdapter#hasNext}})

> Key: IGNITE-16478
> URL: https://issues.apache.org/jira/browse/IGNITE-16478
> Project: Ignite
> Issue Type: Bug
> Reporter: Mirza Aliev
> Priority: Major
> Labels: ignite-3
>
> After investigation of https://issues.apache.org/jira/browse/IGNITE-16406 we
> found a bug in {{PartitionListener#handleScanRetrieveBatchCommand}} when
> leader is changed. In some case, {{cursorDesc.cursor().hasNext()}} returns
> false, hence select operation return empty response, but should response
> several rows.
> Investigation showed that cursor that is returned from
> {{RocksDbPartitionStorage#scan}}
> is inconsistent after leader changing because its hasNext returns unexpected
> false.
> Further investigation is needed.
