> Key: HBASE-16814
> URL: https://issues.apache.org/jira/browse/HBASE-16814
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.2.2, 1.2.3
> Environment: LinuxMint 17.3 (=Ubuntu 14.04), Java 1.8
> Reporter: Hadi Kahraman
>
> FuzzyRowFilter causes ResultScanner.next hang and timeout. The same code
> works well on hbase 1.2.1, 1.2.0, 1.1.4.
> hbase server: cloudera 5.7.0 (hbase 1.2.0) on 4 hosts, 1 master, 3 workers
