Subject [jira] [Created] (HBASE-12435) The exists method on the HTable-class changes the passed-in Get-instance
Date Thu, 06 Nov 2014 07:47:33 GMT
GK Ephorus created HBASE-12435:
----------------------------------

             Summary: The exists method on the HTable-class changes the passed-in Get-instance
                 Key: HBASE-12435
                 URL: https://issues.apache.org/jira/browse/HBASE-12435
             Project: HBase
          Issue Type: Bug
          Components: Client
    Affects Versions: 0.98.6.1
         Environment: Cloudera Hadoop HBase 5.2.0: 0.98.6.?
            Reporter: GK Ephorus


Running an HTable.get right after using HTable.exists using the same instance of a Get-object
yields no results.

Up on inspection of the code we found that the HTable.exists changes the passed-in Get-object.
It changes the property 'checkExistenceOnly' to true which makes the passed-in Get-object
useless for subsequent HTable.get calls.

My suggestion is either:
* indicate this behaviour in the documentation/javadoc
* store the old value of the 'checkExistenceOnly' and restore it using try-finally.
