------------------------------------------
Summary: Null pointer in cassandra.hadoop.ColumnFamilyRecoderWriter
Key: CASSANDRA-8581
URL: https://issues.apache.org/jira/browse/CASSANDRA-8581
Project: Cassandra
Issue Type: Bug
Components: Hadoop
Reporter: xiangdong Huang

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.
