Are you experiencing this? https://issues.apache.org/jira/browse/HBASE-3686
One our guys found and fixed this a while back. This was found with Scans, but since a Gets are implemented as Scans on the RS I thought this might be relevant. -----Original Message----- From: Zhenyu Zhong [mailto:[email protected]] Sent: Tuesday, June 07, 2011 4:34 PM To: [email protected] Subject: HBase Get issue I am using MapReduce job to retrieve records from HTable. Sometimes I experienced issues such as a record exists in the HTable, but the MapReduce job doesn't return one by using Get. The job still finished successfully. During that period, the table might experience some unknown issue, for example, the regions of that table didn't respond. We have to shutdown the regionserver to make them reassigned. (Would that be the problem?) Is there a way to tell the difference between a record in the HTable but fail to return and a record doesn't exist in the table? Best, zhenyu
