Subject [jira] [Commented] (HBASE-7383) create integration test for HBASE-5416 (improving scan performance for certain filters)
Date Tue, 08 Jan 2013 18:04:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7383?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13547061#comment-13547061
] 

Ted Yu commented on HBASE-7383:
-------------------------------

{code}
+   * Generates a deterministic, unique hashed key for a number, so the user can only keep
+   * track of numbers.
{code}
Remove 'only' above.
{code}
+   * @param keyBase Base number for a key, such as a loop counter.
+   */
+  public abstract byte[] getDeterministicUniqueKey(long keyBase);
{code}
Add javadoc for @return. Same for other methods in LoadTestDataGenerator.
{code}
+  public abstract boolean verify(byte[] rowKey, byte[] cf, Set<byte[]> columnSet);
{code}
generateColumnsForCf() returns byte[][], but Set<byte[]> is passed as param above. Can
you explain why the difference ?

For LoadTestKVGenerator:
{code}
+    Random seededRandom = new Random(seed);
{code}
Please use SecureRandom instead.
