[jira] [Commented] (HBASE-12435) The exists method on the
HTable-class changes the passed-in Get-instance
[ https://issues.apache.org/jira/browse/HBASE-12435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14199965#comment-14199965 ]
Anoop Sam John commented on HBASE-12435:
----------------------------------------
The user passed Get object to exist() method can be cloned and used. We do same for Scan object. You want to give a patch?

> 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
> Labels: easyfix
>
> 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.
