Zach,
I wouldn't at all say that doing a count(*) is not recommended. It's important
to know that 1) this requires
different query clients. But how do I set a high timeout so that I
can do a large query via Java/JDBC?
Thanks!

Server side HBase properties such as hbase.rpc.timeout need to be set in your

Server side HBase properties such as hbase.rpc.timeout need to be set in your
hbase-sites.xml. There's no API to set these.
The phoenix.query.timeoutMs can be set using
http://docs.oracle.com/javase/7/docs/api/java/sql
I wrote a Java program that runs nightly and collects metrics about our hive
tables.
I would like to include HBase tables in this as well.
Since select count(*) is slow and not recommended on Phoenix, what are my
alternatives from Java?
Is there a way to call
RowCounter is s mapreduce program. After the program completes execution of
the job, it returns information about that job, including job counters.
RowCounter includes its counts in the job counters, so they're easily
accessed programmatically from the returned object. It's not a ResultSet,
but it
Zach,
I wouldn't at all say that doing a count(*) is not recommended. It's
important to know that 1) this requires a full table scan and 2) this is
done by Phoenix asynchronously. You'll need to set the timeouts high enough
for this to complete. Phoenix will be much faster than running a MR job,
