Shubhangi Pardeshi updated FLUME-3212:
--------------------------------------
Description:
Flume agent fails with FlumeException if configuration file contains comments
after property value in same line (i.e. as follows)
{code:java}
<property> = <value> #comment
{code}
i.e. config parameter value pair followed by comment
This is because flume is not ignoring these comment.
{code:java}
Example.
[root@cnode2 flume]# grep -i comment flume.conf
a1.sources.r1.type = netcat # this is inline comment
{code}
Produce below error in log
{code:java}
org.apache.flume.FlumeException: Unable to load source type: netcat # this is
inline comment, class: netcat # this is inline comment

org.apache.flume.source.DefaultSourceFactory.getClass(DefaultSourceFactory.java:68)

{code}
Ideally flume should ignore comment while parsing configuration file and agent
should start successfully. Or config file parsing related error should be
thrown.
