> Add description for dfs.namenode.caching.enabled
> ------------------------------------------------
>
> Key: HDFS-16209
> URL: https://issues.apache.org/jira/browse/HDFS-16209
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.1.0
> Reporter: tomscut
> Assignee: tomscut
> Priority: Major
> Labels: pull-request-available
> Time Spent: 2h 40m
> Remaining Estimate: 0h
>
> Namenode config:
> dfs.namenode.write-lock-reporting-threshold-ms=50ms
> dfs.namenode.caching.enabled=true (default)
>
> In fact, the caching feature is not used in our cluster, but this switch is
> turned on by default(dfs.namenode.caching.enabled=true), incurring some
> additional write lock overhead. We count the number of write lock warnings in
> a log file, and find that the number of rescan cache warnings reaches about
> 32%, which greatly affects the performance of Namenode.
> !namenode-write-lock.jpg!
>
> We should set 'dfs.namenode.caching.enabled' to false by default and turn it
> on when we wants to use it.
