<https://reviews.apache.org/r/2029/#comment5082>
an extra indent?
src/main/java/org/apache/hadoop/hbase/HServerLoad.java
<https://reviews.apache.org/r/2029/#comment5083>
Just a naming suggestion for walCoprocessors=>coprocessors. Although right
now WALObserver is the only RS level CP, but it'd better not to indicate here.
src/main/java/org/apache/hadoop/hbase/HServerLoad.java
<https://reviews.apache.org/r/2029/#comment5085>
getSimpleName() only returns the class name w/o package info. I think we
should use the whole class name for the comparator.
src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/2029/#comment5092>
do we really need to provide it thru HTAdmin? if we do, the returned value
is not correct in case of exception.
src/main/java/org/apache/hadoop/hbase/ipc/HMasterInterface.java
<https://reviews.apache.org/r/2029/#comment5087>
The new method is a little odd. how about just getCoprocessors().
src/main/java/org/apache/hadoop/hbase/master/HMaster.java
<https://reviews.apache.org/r/2029/#comment5091>
still the method name?
src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
<https://reviews.apache.org/r/2029/#comment5096>
same as HMasterInterface. can we just generateCoprocessorString() => String
getCoprocessors()?
src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
<https://reviews.apache.org/r/2029/#comment5097>
is it okay just reuse the existing serverLoad, without rebuilding the whole
thing?
this.serverInfo.getLoad()
but it may not be a big issue.
src/test/java/org/apache/hadoop/hbase/coprocessor/TestCoprocessorEndpoint.java
<https://reviews.apache.org/r/2029/#comment5098>
The file TestCoprocessorEndpoint is particularly for testing cp endpoint.
It's odd to put the new test cases to this file. Maybe TestClassLoading is a
better place.
src/test/java/org/apache/hadoop/hbase/coprocessor/TestCoprocessorEndpoint.java
<https://reviews.apache.org/r/2029/#comment5100>
according the previous override comparator in HRL, the cps should be in
alphabet order. so you don't need to compare this 2 strings.
