kanaka kumar avvaru commented on HDFS-8477:
-------------------------------------------
I have initially added a note as shown below to
{{HDFSHighAvailabilityWithQJM.md}}, but felt may not be required to specify
explicitly as many other ports were not described either in site document files
{code}
*Note:* ZKFC uses 8019 as the default port which is configurable by modifying
the parameter `dfs.ha.zkfc.port` in `hdfs-site.xml` file.
Also, ZKFC health monitor uses `dfs.ha.zkfc.nn.http.timeout.ms` configuration
for http time out during NameNode thread-dump which is by default 20
seconds(configuring value as 0 would turn off the thread dump).
{code}
Can anyone please confirm me about changing {{HDFSHighAvailabilityWithQJM.md}}
is required or not?
> Missing ZKFC config keys can be added to hdfs-default.xml and
> HDFSHighAvailabilityWithQJM.md
