Subject [jira] [Commented] (HBASE-17280) Add mechanism to control hbase cleaner behavior
Date Fri, 27 Jan 2017 21:30:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15843517#comment-15843517

Ted Yu commented on HBASE-17280:
--------------------------------


+   * @param enable if true enables the cleaner
+   * @return the previous state
+   * @throws MasterNotRunningException
+   */
+  public boolean setCleanerChoreRunning(final boolean on) throws IOException;

Correct name of parameter in javadoc - on, not enable.

+                 .setCleanerChoreRunning(getRpcController(), RequestConverter.buildSetCleanerChoreRunningRequest(on))

Indentation is two spaces per indent. Line length should be no longer than 100

+  public static RunCleanerChoreRequest buildCleanerChoreRequest() {
+    return CLEANERCHORE_REQUEST;

The request is to run cleaner. Name the method buildRunCleanerChoreRequest

Name cleaner_enabled.rb cleaner_chore_enabled.rb

Name cleaner_run.rb cleaner_chore_run.rb

Name cleaner_switch.rb cleaner_chore_switch.rb

> Cleaner is used to get rid of archived HFiles and old WALs in HBase.
> In the case of heavy workload, cleaner can affect query performance by creating a lot
of connections to perform costly reads/ writes against underlying filesystem.
> This patch allows the user to control HBase cleaner behavior by providing shell commands
to enable/ disable and manually run it.
