Ryan Merriman created METRON-757:
------------------------------------
Summary: Colocation of Hadoop and HBase clients with Storm worker
nodes not enforced
Key: METRON-757
URL: https://issues.apache.org/jira/browse/METRON-757
Project: Metron
Issue Type: Bug
Reporter: Ryan Merriman
The parser topology has a dependency with HDFS when configured with a
GrokParser. If the host running the GrokParser doesn't have a Hadoop Client
installed (in Ambari terms), the local file system will be used instead and
this message is logged:
Java.lang.RuntimeException: Grok parser Error: Grok parser unable to initialize
grok parser: Unable to load /apps/metron/patterns/ranger from either classpath
or HDFS
The MPack should ensure all Storm worker nodes have the Hadoop and HBase
clients installed.
