[jira] [Commented] (HBASE-8008) Fix DirFilter usage to be consistent

["Ted Yu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-8008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13593814#comment-13593814 ] 

Ted Yu commented on HBASE-8008:
-------------------------------

{code}
+   * A {@link PathFilter} that returns usertable directories. To get all directories use the
+   * {@link BlackListDirFilter} with a <tt>null</tt> blacklist
+   */
+  public static class DirFilter extends BlackListDirFilter {
+
+    public DirFilter(FileSystem fs) {
+      super(fs, null);
+    }
+  }
+
+  /**
+   * A {@link PathFilter} that returns usertable directories. To get all directories use the
+   * {@link BlackListDirFilter} with a <tt>null</tt> blacklist
+   */
+  public static class UseTableDirFilter extends BlackListDirFilter {
+
+    public UseTableDirFilter(FileSystem fs) {
+      super(fs, HConstants.HBASE_NON_USER_TABLE_DIRS);
{code}
The javadoc for both methods seems to be the same.

For UseTableDirFilter, I guess you meant UserTableDirFilter

> Currently the DirFilter automatically filters out HConstants.HBASE_NON_USER_TABLE_DIRS, which is not needed in most cases. We should switch the usage so people actually using a directory filter and then have a special filter when looking for tables specifically.
