Efficient way to read a large number of files in S3 and upload their content to HBase - HBase - [mail # user]
...This is a question I see coming up a lot. Put differently: what characteristics make it useful to use HBase on top of HDFS, as opposed to just flat files in HDFS directly? "Quantity" isn't r...

HBase logging only prints ulimit information - HBase - [mail # user]
...How did you end up figuring that out, Kevin? Was there a more ominous message in the logs about this? Should have logged something like:  "WARNING: Server foo has been rejected; Reporte...

key design - HBase - [mail # user]
...Mete,  Why separate tables per log type? Why not a single table with the key:    That's roughly the approach used by OpenTSDB (with "metric id" instead of "log type", but same...

getting real, does hbase need constant mothering or can a 1-man show use it? - HBase - [mail # user]

understanding the code base, patterns, threading, etc. - HBase - [mail # dev]
...Well, the first answer is always the same: read the code! :)  Of course, sometimes it's difficult to get the high level concepts quickly that way (even with good docs, like the HBase co...

hbase as a primary store, or is it more for "2nd class" data? - HBase - [mail # user]
...Ahmed,  Generally speaking, the intent of HBase IS to be a first class data store. It's a young data store (not even 1.0) so you have to take that into account; but there's been a lot o...

Overwriting qualifiers in an existing table - HBase - [mail # user]

More tables, or add a prefix to each row key? - HBase - [mail # user]

Performance issues of prepending a table - HBase - [mail # user]
...I would guess that this approach would be susceptible to the same kind of "hot spotting" as inserting sequential keys; if you're prepending globally (i.e. there's one global "first" row), th...

Is htable.delete(List<Delete>) transactional? - HBase - [mail # user]
