-------------------------------------
Summary: flume-0.9.4: encounter "java.io.IOException: Unexpected
exception in loadConfigs" when start flume master
Key: FLUME-1195
URL: https://issues.apache.org/jira/browse/FLUME-1195
Project: Flume
Issue Type: Bug
Components: Configuration
Affects Versions: v0.9.4
Environment: VM, Linux
1 master node, 8 agent node
zookeeper:3 nodes
Reporter: fang fang chen
-- I am using external zookeeper to run flume. During start flume master
node, I got following error information in flumemaster.out. And we can find
flume master has been started by pid files.
-- But when run "refreshAll" in flume shell, the command failed with "Could
not increment version counter...".
-- When run flume without external zookeeper, flume can work normally. So I
assume this is caused by zookeeper part.
Here is the zookeeper configuration: node1 is hostname and node2/node3
is ip.
<property>
<name>flume.master.zk.servers</name>
<value>node1:2181,node2:2181,node3:2181</value>
</property>
</configuration>
