Subject [jira] [Commented] (CASSANDRA-8581) Null pointer in cassandra.hadoop.ColumnFamilyRecoderWriter
Date Tue, 08 Dec 2015 21:40:11 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15047511#comment-15047511
] 

Philip Thompson commented on CASSANDRA-8581:
--------------------------------------------

So as far as I can tell, running examples/hadoop_word_count on 2.1.12 works just fine. I don't
quite see anything wrong with this patch, but I also don't know that it's necessary.

> When I run examples/hadoop_word_count. I find that ReducerToFilesystem is correct but
when I use ReducerToCassandra, the program will call loadYaml().
> The reason is that the program catch a exception at line 196 of ColumnFamilyRecoderWriter.java.

> Then it check why the exception occur, then it loadYaml to check if the disk is broken...
> However, the exception is NullPointerException. because the client is not initialized.
>  
> So we need a check to judge whether the client is null.

> The exception, original code and fixed code are in the attachments.
