Hari Shreedharan updated FLUME-1137:
------------------------------------
Description:
RecoverableMemoryChannel needs Hadoop IO classes in classpath. On a machine
where Hadoop isn't on Classpath, Class.forName throws NoClassDefFoundError,
which is not caught by the factory class, causing the agent startup to fail. It
is not exactly a good idea to expect every machine on which this channel will
be used to have Hadoop installed. We currently depend on Hadoop/HDFS only where
we are actually writing to HDFS. Even the JDBC channel has an embedded DB, thus
not requiring the DB to be available in classpath.
The same is true for the File Channel as well.
