Character '*' precedes character '0'
Probably that was why some rows were not returned.
How long is the third component (number) normally ?

Serega:
How often is major compaction run in your cluster ?
Have you configured offpeak compaction ?
See related parameters in:

Hi Serega,
How iostat looks like? are you seeing high utilization (above 60% across
the drives) or long await write times when its writing to the WAL? What
else do you see in the RS logs?
cheers,

Hi Serega, can also be because of garbage collection.
Can you share the logs around the time this occurs?
Compacting regions will not block HBase to get writes and to write in the
WAL. But might impact your storage system regarding IOs.

Hi, we have 10 nodes cluster running HBase 0.98 CDH 5.2.1
Sometimes HBase stucks.
We have several apps constantly writing/reading data from it. Sometimes we
see that apps response time dramatically increases. It means that app
spends seconds to read/write from/to HBase. in 99% of time it takes

Did you send the logs from one of those 3 servers? [5.9.41.237:50010,
5.9.77.105:50010, 5.9.73.19:50010]
Sound like something is slowing done everything. Can you extract DN logs
for the same time?
Do you have any tool monitoring the disks and network latency over time?
If not, can you run

Hi Everyone,
We have BigDataDayLA coming up on 27/6/2015 Los Angeles, CA.
We are looking for speakers on NoSql track, so we thought of reaching HBase
and Phoenix user groups to see if anyone is interested. You can submit your

My rowkey format is uniqueid|timestamp|randomnumber.
I want to retrieve data from hbase by using scanner with java api where my
startRow : aabb|timeStamp1|
stopRow is : aabb|timeStamp2|*any_number
timeStamp1 and timeStamp2 are time ranges. So I want to fetch all values in
between above
I see that you are already using partial key scan approach.
When you say that you want data from the timeStamp2 as well, you want all
the rows from timeStamp2? Also, how are you actually setting the stopRow?
What are you providing for the *anyNumber field when you are setting
stopRow?
e.g. if

If u want data of timeStamp2 also, (All 6 rows as shown in eg: above) then
you have to put timeStamp3 in stop row.. The stop row is exclusive.
startRow : aabb|timeStamp1|
stopRow is : aabb|timeStamp3
