What about adding a simple message box using bash's whiptail?
For example:
rs=$(cat ${HBASE_CONF_DIR}/regionservers | xargs)
if ( whiptail --yesno Do you want to shutdown the cluster with the
following regionserver $rs\n[y/n] 10 40 )
then
# proceed with the shutdown
else

Hi J-D,
If 1GB region size and about 1K regions per server is recommended, does
that mean that a region node should server about 1TB of compressed data
at most?
If that is the case than having more than 2TB (1TB for data and 1TB of
spare free space) is wasteful for data nodes that are part
Hi Stack,
OK, I will up it to 1GB. Do I need to do a full restart or rolling RS
restarts will do?
I have been happy with 0.20.3 even though it is an ancient release.
Given that we have a 0.3-man team dedicated to HBase it is hard to find
time for upgrades. It will have to wait for 0.90 or
Hi Stack,
We have been running a small cluster (name node + 5 rs) on 0.20.3 for a
long time now. We are currently at 1100 regions per RS. As far as I can
tell, I have not seen any problems or changes in behavior due this.
What kind of problems can I expect with 1K+ regions per RS? What is a
We want to start benchmarking the mutliget feature (HTable.batch).
However, I don't see it in the latest 0.89 :( Is this something that we
need to test against the trunk? Thanks.

Are there any firewalls in place ? Are you running thrift servers on the
same nodes as region servers? What kind of exception do you get?

One thing that I can think of is to sort measurements from the newest to
oldest:
DevA,12pm,150W
DevA,9am,100W
Now instead of scanning from-to date, start with the to date and keep
scanning until you find a row with a date that is older than the from date.
To use your example, start the scan
