Subject [jira] [Commented] (HBASE-16198) Enhance backup history command
Date Thu, 04 Aug 2016 16:33:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15408066#comment-15408066
] 

Ted Yu commented on HBASE-16198:
--------------------------------

{code}
+  private static final String HISTORY_CMD_USAGE = "Usage: hbase backup history [-path BACKUP_ROOT]
[-n N] [-t table]\n"
{code}
Wrap long line.
{code}
+    private Path getBackupRootPath() {
+      String value = cmdline.getOptionValue("t");
{code}
Is the above right ? "t" is for table name, right ?

Is there any change in BackupManifest.java since it is moved to hbase-client package.
{code}
+  public static List<BackupInfo> getHistory(Configuration conn, Path backupRootPath)
throws IOException {
{code}
Please name Configuration parameter conf (or similar).
{code}
+        } else {
+          //TODO
+          return -1;
{code}
What's the plan for the above case ?
{code}
+      List<BackupInfo> history = table.getBackupHistoryForTable(name);
{code}
Is it possible to pass n into the above method so that fewer rows are retrieved from backup
table ?
