Enis Soztutar commented on HBASE-17556:
---------------------------------------
There has been several fixes in that area. Which exact version of the client
are you using?
> The client will not invalidate stale region caches

> Key: HBASE-17556
> URL: https://issues.apache.org/jira/browse/HBASE-17556
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.0.0, 2.0.0, 0.98.24
> Reporter: Marcin Januszkiewicz
> Priority: Critical
>
> We noticed in our application, that sometimes when we interact with a table
> an operation will fail with an exception, an all operations that happen on
> the same region will also fail until the application is restarted.
> It seems that when a merge or split happens on a region that is already in
> the clients cache, and the client is configured to retry operations, then
> there is no way for the client to detect this. In
> RpcRetryingCaller#callWithRetries if a call fails with
> RegionNotServingException then the cache will be cleared only if the retry
> parameter is equal to 1. This means the call will fail but the following
> calls will succeed.
> RpcRetryingCaller#callWithoutRetries contains the comment "It would be nice
> to clear the location cache here". Additionally, the stale cache will cause
> this call to fail, even though the data is available.
