Please enclose the assignment on line 292 in curly braces.
/src/main/java/org/apache/hadoop/hbase/ServerName.java
<https://reviews.apache.org/r/3308/#comment9580>
Since IPv4 support is built in, I suggest naming this method isValidHost.
/src/main/java/org/apache/hadoop/hbase/ServerName.java
<https://reviews.apache.org/r/3308/#comment9581>
Why the extra line here ?
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9587>
I think threadPool is a better name for this field.
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9582>
I think Async is unnecessary here - that's what threads provide.
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9584>
Why not call tableExists() directly ?
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9583>
Should include the actual name passed in exception message.
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9585>
Should read 'Exception parsing server name'
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9586>
Since serverToRegionsMap has been created, you can return
serverToRegionsMap here.
/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
<https://reviews.apache.org/r/3308/#comment9588>
regions could be empty, right ?
/src/main/java/org/apache/hadoop/hbase/ipc/HRegionInterface.java
<https://reviews.apache.org/r/3308/#comment9589>
This and flushAllRegions() are similar.
Can we introduce just one new method which checks whether the list is empty
to decide what to do ?
i.e. move the check @ line 1403 of HBaseAdmin to the implementation of the
new method.
/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
<https://reviews.apache.org/r/3308/#comment9590>
Curly braces, please.
/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
<https://reviews.apache.org/r/3308/#comment9591>
Do we need to place a try/catch block around line 2795 ?
Currently the first failure would stop subsequent flushes.
