Trevor Powell commented on HADOOP-7750:
---------------------------------------
Good Day,
I have jsvc under $hadoophome/libexec/
$ ls -l
total 100
-rwxr-xr-x 1 root root 52776 Oct 13 10:51 jsvc.amd64
-rwxr-xr-x 1 root root 42624 Oct 13 10:51 jsvc.i386
I figured this was good looking at the hadoop script.
hadoop: exec "$HADOOP_HOME/libexec/jsvc.${JSVC_ARCH}"
As for my DN ports I have this:
<!-- DataNode security config -->
<property>
<name>dfs.datanode.address</name>
<value>0.0.0.0:1004</value>
</property>
<property>
<name>dfs.datanode.http.address</name>
<value>0.0.0.0:1006</value>
</property>
Thoughts?
