Xiaoyu Yao commented on HDFS-11036:
-----------------------------------
Thanks [~vagarychen] for working on this. The patch looks good to me overall. I
just have a few suggestions below:
*XceiverClientManager.java*
Line 53: Can we use guava CacheBuilder here to simplify the code?
You can refer to the KeyProvdierCache as an example.
Line 63: should be "If a connection has <<not>> been accessed"
Line 108/111: can we use the conf.getTimeDuration() to time related
configuration?
> Ozone : reuse Xceiver connection
