Subject [jira] [Commented] (HBASE-10948) Fix hbase table file 'x' mode
Date Wed, 09 Apr 2014 18:04:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13964479#comment-13964479
] 

Jerry He commented on HBASE-10948:
----------------------------------

Here is the java doc comment 
{code}
  /**
   * Get the default permission for directory and symlink.
   * In previous versions, this default permission was also used to
   * create files, so files created end up with ugo+x permission.
   * See HADOOP-9155 for detail. 
   * Two new methods are added to solve this, please use 
   * {@link FsPermission#getDirDefault()} for directory, and use
   * {@link FsPermission#getFileDefault()} for file.
   * This method is kept for compatibility.
   */
  public static FsPermission getDefault() {
    return new FsPermission((short)00777);
  }
{code}
