The first hbase 0.90.0 release candidate is available for download:
http://people.apache.org/~stack/hbase-0.90.0-candidate-0/
HBase 0.90.0 is the major HBase release that follows 0.20.0 and the
fruit of the 0.89.x development release series we've been running of
late.
More than 920 issues have
Just a few findings when I tried to compile our 0.20.6 based code with this
new release:
HConstants is final class now instead of interface
RowFilterInterface is gone
org.apache.hadoop.hbase.io.Cell is gone
org.apache.hadoop.hbase.io.RowResult is gone
constructor
Were all of the removed classes marked @Deprecated in 0.20? If not, we need
to make sure they survive somehow in 0.90 IMO.

That is correct, those classes were deprecated in 0.20, and now gone in 0.90.
Now you will want to use HTable and Result.
Also Filter.getNextKeyHint() is an implementation detail, have a look
at the other filters to get a sense of what it does.

I think it's worth going at greater lengths to document that kind of
breakage, maybe a page in the book? Stuff like What's new and
Incompatibilities that we can easily link to.

We used the following code to see if the Cell (pardon me for using the old
term) returned from scanner was of certain timestamp:
if (result.getCellValue().getTimestamp() == ts){
In 0.90, I don't see method which returns the timestamp for Result.
I am wondering if the above check can

Ted is looking for. Its pegged against 0.90.1 but if a new RC, we can
include it then.

Since there may be more than one qualifier for a column family, is it
reasonable to add Result.getColumnLatest(byte[]) which returns the latest
column for given family ?
Thanks

Within a Result object you are only going to get columns for a
single row. So the 2 byte[] are family and qualifier. Check the
javadoc. I wrote quite a bit of documentation on these APIs.

Why are you calling this method?
Despite it being 'public', users are not expected to talk to the
filesystem directly. Your Warranty would be void if you did so :-)

Hi,
Sorry I dont have enough context here. The region name format is
designed to be semi-backwards compatible, so you should be able to use
'true' for the new field and use the resulting string in searches in
META even with old region names in META.
