Hi,
I would like to confirm my understand.
Let's say I have 13 column families in a hbase table. 11 of those column
families have no data, which 2 column families have large amount of data.
My understanding is that the size of memstore, which is 128M in my env,
will be shared across all column f
Hi,
Is there an easy way to check if a column family of a hbase table has any
data?
I try something like "scan '', { LIMIT => 10,
FILTER=>"FamilyFilter(=, 'binary:')" } in hbase shell and it
timeout. I guess it's because my table
has 15TB of data. So, I am guessing that particular family has no d
Hello,
As I understand, the deleted records in hbase files do not get removed
until a major compaction is performed.
I have a few questions regarding major compaction:
1. If I set a TTL and/or a max number of versions, the records are older
than the TTL or the
expired versions will still

Hi,
When taking a snapshot or running the export utility, is it possible to
specify a condition or filter on some columns so that only rows that
satisfy the condition will be included in the snapshot or exported?
Thanks.

Forgot to mention that all regions of the table is offline now. Wondering
if the table will eventually got disable as it has been running for almost
24 hrs now.
Thanks.
Antonio.

Hi,
We have a table which is stuck in FAILED_OPEN state. So, we planned to drop
the table and re-clone the table from an old snapshot. We disabled the
table, but the disable procedure has been running for more than 20 hrs.
I went to hbase shell and found out "is_disabled" and "is_enabled" both

Hello,
I have a hbase table whose definition has a max number of versions set to
36000.
I have verified that there are rows which have more than 2 versions
saved.
Now, I change the definition of the table and reduce the max number of
versions to 18000. Will I see the size of the table being r

Hi,
When I run org.apache.hadoop.hbase.mapreduce.*CellCounter*, I am getting Timed
out after 600 secs. Is there a way to override the timeout value rather
than changing it in hbase-site.xml and restart hbase?
Any suggestions would be helpful.
Thank you.
Antonio.

Hi,
I am new to hbase. I am wondering how I could find out which rowkey has the
largest number of versions in a column family.
Any pointer would be very helpful.
Thanks.
Antonio.
