You're doing nothing wrong.
The filters as written recurse until they find a match. If long
stretches between matching rows, then you will get a
StackOverflowError. Filters need to be changed. Thanks for pointing
this out. Can you do without them for the moment until we get a chance
to fix it? (HBASE-554)
Thanks,

Hi St.Ack and all
The error always occurs when trying to see if there are more rows to
process.
Yes I'm using a filter(RegExpRowFilter) to select only the rows (any
row key) that match a specific value in one of the columns.
Then I obtain the scanner just test the hasNext method, close the
scanner and return.
Am I doing something wrong?
Still StackOverflowError is not supposed to happen right?

Hi guys
I 'm using HBase to keep data that is later indexed.
The data is indexed in chunks so the cycle is get XXXX records index
them check for more records etc...
When I tryed the candidate-2 instead of the old 0.16.0 (which I
switched to do to the regionservers becoming unresponsive) I got the
error in the end of this email well into an indexing job.
So you have any idea why? Am I doing something wrong?
