Using correct mailing list this time.
I last worked on 0.90.x code base back in 2011 (or earlier)
So I need to pull down 0.90 source code before giving you an answer.
bq. the next planned environment upgrade is towards the 2nd half of this
year
Please convey to management that the upgrade should
Sounds like lost HFiles. I'd start digging through the HDFS logs.
Which version of Hadoop/HDFS are you using. Any power outages, recently?

In a hbase cluster, all the slave nodes got restarted. When I started Hbase
services,
one of the table(test) become inconsistent.
HDFS some blocks were missing(hbase blocks). so it was in safe mode. I gave
"safemode -leave"
Then hbase table (test)became inconsistent.
Below actions I performed

Hi Lars,
This is very mysterious for us Some rows are completely deleted, some
of them are partially deleted with one CF present and other CF partially
present or not.
The regions which are once around 7gb has turned to few KB's, so it is a
major data loss for us... and We suspect they also
Where can i get more information about these structures ?
Thanks and Regards,

Which one of the storage structure does hbase uses ? Is it LSM tree ,
SSTable or fractal tree ?

You should be passing the obtained rowLock object as parameter for the
Constructor of put object.
