[jira] Updated: (HADOOP-1637) [hbase] Fix to HScanner to Support
Filters, Add Filter Tests to TestScanner2
[ https://issues.apache.org/jira/browse/HADOOP-1637?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Izaak Rubin updated HADOOP-1637:
--------------------------------
Attachment: HADOOP-1637.patch
This patch makes the necessary changes to HScanner such that it now correctly handles filters. Additional tests are also added to TestScanner2 to confirm this new functionality.
The tests in TestScanner2 depend on the filters package having been updated with the patches in HADOOP-1579 and HADOOP-1606. Both of these patches should be committed before HADOOP-1637.
For clarification, the order in which these three issues should be committed is:
HADOOP-1606
HADOOP-1579
HADOOP-1637
All HBase tests have passed successfully. At present the test:
org.apache.hadoop.streaming.TestSymLink
is not functioning. Nonetheless all preceding HADOOP tests are passing, and this particular test in no way reflects on the functionality and compatibility of HBase within HADOOP.

> HScanner has a non-functional support for filters. Upon writing scanner tests for filters in TestScanner2, I discovered that HScanner only increments each of its sub-scanners when the filtering decision is false. Until now this has not been a problem, because none of the other processes that use HScanner also use filters. The patch to be posted will fix the HScanner incrementation problem, and add testing for filters to TestScanner2.
