Left some comments for hbtop. Most of them are small nits. I have a question. It looks like this PR includes the changes of HBASE-15519, right? You are assuming that after committing the PR of HBASE-15519, we will commit this PR?

brfrn169 · 2019-10-20T16:20:28Z

And don't we need ClientModeTest?

joshelser

Need to take this down locally and play with it too :)

Probably not a bad idea to also run this through a quick perf test to make sure no regressions come in (same way as the dependent user metrics change)

+ * @param countField Field which needs to be added with value 1 for each record
+ * @return records after selecting required fields and adding count field
+ */
+ public static List<Record> selectModeFieldsAndAddCountField(List<FieldInfo> fieldInfos,


Instead of doing this in one fatal swoop, could you split this method into two parts?
pseudo-code-y
.map(Record::select) .map(Record::addCountField)
I guess this would undo the optimization you're trying to make of copying Record objects?

Yeah, Let me see if I can make it more readable.

Thank you @brfrn169 and @joshelser for the review. Have pushed the commit addressing most of the review comments.

apurtell

One nit and a question. I defer comment on hbtop internal changes to @brfrn169

ankitsinghal · 2019-10-30T02:53:31Z

./bin/ycsb run hbase20 -P workloads/workloada -s -threads 10 -p columnfamily=family

ycsb shows performance similar on single server cluster with and without patch.

I tested this locally and found some bugs. Left some comments for that.

I think this feature should be great for HBase administrators. Thank you! @ankitsinghal

Left a comment that's a very small nit. It looks good to me 👍 Thanks! Ankit

 if (!filters.isEmpty()) {

We don't need this line :)

OK by me. I know Ankit was traveling with intermittent access. I think he might be back soon, but I don't think you need to wait for him if you think this is good.
