Date Wed, 17 May 2017 19:56:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16014683#comment-16014683

Chen Liang commented on HDFS-11832:
-----------------------------------

Thanks [~10075197] for updating the patch! I tested v002 patch locally and all tests passed,
so the failed tests should be unrelated.

> HDFS-7706 Switch BlockManager logging to use slf4j. But the logging formats were not
modified appropriately. For example:
>       if (LOG.isDebugEnabled()) {
>         LOG.debug("blocks = " + java.util.Arrays.asList(blocks));
>       }
> These codes should be modified to:
>       LOG.debug("blocks = {}", java.util.Arrays.asList(blocks));
