Hi Jon,
sorry I forgot to include the details of our environment. We are using
cdh3u3, which includes the patch (I think cdh3u2 did not). I went a bit
through the patches for the two issues (HBASE-4196) and (HBASE-4269) and
I think the problem is that the patch to HBASE-4196 did not change
I install habse in standalone and I don't install Hadoop.

You will need the hadoop jar for this. Hbase uses hadoop for common stuff
like the configuration you've seen, so even a simple client needs it.

You will need the hadoop jar for this. Hbase uses hadoop for common stuff
like the configuration
only jar files. They are already in the hbase distrib (i.e. if you download
hbase, you get the hadoop jar files you need). You just need to import them
in your IDE.

Jiajun,
Your problem isn't coprocessor related, per those logs. It appears
that one of the regions Master tried to look up in your .META. entries
had no region info associated with it (and hence got a null). Before
upgrading, did your hbck report proper health? Does your master not
start at all
Hi there-

Hi,
Yes and no.
No, because as a table can have millions of columns and these columns can
be different for every row, the only way to get all the columns is to scan
the whole table.
Yes, because if you scan the table you can have the columns names. See
Result#getMap: it's organized by family --

I think you want to know about the following methods:

Hi Laxman,
can you clarify what you mean by duplicates?
The TreeSet is using KeyValue.COMPARATOR,which treats KVs as the same only if
the entire key (including column and timestamp) is the same.
Do you have KVs with the same rowKey, columnKey, and timestamp, but different
values?
Thanks.

Your post is missing the most important configurations, mainly the
region server heap size and GC configs.
Also, how much of those 300GB do you need to serve? Does the working
dataset fit in cache?
