In 0.90, HBaseAdmin.flush() uses a loop to go over ListPairHRegionInfo,
HServerAddress
Should executor service be used for higher parallelism ?
Thanks
Our dev cluster has 8 nodes.
hadoop0: NN, JT, zookeeper quorum
hadoop8: TT, HMaster
hadoop4: RS
All other nodes run RS and TT
Is there inherent issue with this setup ?
Thanks

Hi Stack,
That's a start. Let's try it with the CP issue and try to get a report going?

Hi,
I wanted to let you know that I'm planning to contribute the following items to
the HBase community. These are my spare time projects and I'll only be able to
spend my time about 7 hours a week, so the progress will be very slow. I want
some feedback from you guys to prioritize them.
#1 looks similar to what MapR has done.

Hopefully to do #1, you would not require many/any changes in HFile or
HBase. Implementing the HDFS stream API should be enough.
#2 is interesting, what is the benefit? How did you measure said benefit?

In 0.90 region server log, I got:
grep 'Got brand-new compressor'
hbase-hadoop-regionserver-sjc1-hadoop2.sjc1.carrieriq.com.log | wc
435933 3051531 41413635
I wonder if the above led to degraded performance.
On the same regionserver:
libgplcompression.so libhadoop.a libhadoop.la
That happened to me when using GZ compression without the native compression
libraries installed properly. You must add them to hbase .90 manually.
Without them it uses the pure-java gzip successfully, but I think hadoop
has a logging bug and prints out the message too often.
