[jira] Created: (HBASE-2179) get performance problem with concurrent reads

get performance problem with concurrent reads
---------------------------------------------

                 Key: HBASE-2179
                 URL: https://issues.apache.org/jira/browse/HBASE-2179
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: ryan rawson
            Assignee: ryan rawson
             Fix For: 0.21.0


a get obtains a row lock before reading, which then blocks all other gets and puts to that row. on highly concurrent rows this reduces our performance and needlessly serializes reads.
