Is there any place where hdfs command history is stored on lines
.bash_history in shell. Since the regions have increased for the table
about 100 over a night (From 120 to 211)... I am suspecting that some thing
is wrong from hbase side...

TTL setting is Integer.MAX_VALUE. so it should not be problem.

Hi Kiran,
Can you check your table TTL setting? Is it possible that the data are
expired and purged?
Thanks,
Jimmy

Hi Jean,

Hi Kiran,
2 things.
1) Is there any reason for you to use a so old HBase version? any chance to
migrate to a more recent one? 0.94.17 is out.
2) What do you mean by "I have never seen a wierd start key and end key
like this"? I don't see anything wrong with what you described. What you
keys look
Adding to that there are many regions with 0MB size and have CF's as
specified in the table...

Hi All,
We have been experiencing severe data loss issues from few hours. There are
some wierd things going on in the cluster. We were unable to locate the
data even in hdfs
Hbase version 0.94.1
Here is the wierd things that are going on:
1) Table which was once 1TB has now become 170GB with ma
13 matches
