You don't find them, you set them up.
ZOOKEEPER_HOSTNAME being the name of the host where zookeeper is running 
and HDFS_HOSTNAME the name of the host where the namenode is running.

Hi Bruno,

Thank you very much for your email. It gives me hope ;).
Would you mind to tell me how I can find  ZOOKEEPER_HOSTNAME and
  HDFS_HOSTNAME in bigtop.
I suppose that HDFS_HOSTNAME is already started but it is also valid
for ZOOKEEPER_HOSTNAME?
How can I check that ?

Sorry for the funny questions but I am just perfect beginer. Hope thanks
Bigtop not very long ;)

Thank you once again and
Cheers,
Ivo

Dear All,

I installed bigtop 0.7.0 but after every restart of my computer
there is
a message that
/tmp folder can not be found. HBase tables are also deleted
after reset.

I tried to see configuration for the /TMP folder but when I start
ivo@ivo-Aspire-3830T:/usr/lib/__hadoop-hdfs/bin$ dpkg -L hadoop

/etc/hadoop/conf.empty
/etc/hadoop/conf.empty/__configuration.xsl
/etc/hadoop/conf.empty/hadoop-__env.sh
/etc/hadoop/conf.empty/ssl-__client.xml.example

and these files are empty.
Would you mind to tell me how I can start hadoop in pseudo mode
and to
configure the right directory for tmp to be able to keep HBase
tables.
Thank you very much!

Hi Ivaylo,

Apache HBase package do not come with a pseudo conf package and that
is something I hope to fix at the next hackathon.
Also by default and if I remember correctly, Apache HBase will write
on disk on /tmp.

So you may want to look into Apache HBase documentation in order to
configure Apache HBase accordingly to your setup. Apache Bigtop
puppet recipes may also help since they provide working
configuration for a distributed cluster.

if it helps, here is a simple configuration I use sometimes for
hbase-site.xml:

configuration

   property
 namehbase.cluster.__distributed/name
   valuetrue/value
   /property

   property
 namehbase.zookeeper.quorum/__name
   valueZOOKEEPER_HOSTNAME/__value
   /property

   property
 namehbase.rootdir/name
   valuehdfs://HDFS_HOSTNAME:__8020/hbase/value
   /property

   property
 namedfs.support.append/__name
   valuetrue/value
   /property


/configuration

Please replace ZOOKEEPER_HOSTNAME and HDFS_HOSTNAME accordingly.
You can also replace the value of hbase.rootdir by a local directory
if you do not want to go through Apache Hadoop HDFS.



Thanks,
Bruno

Re: East coast bigtop hackday/microtalks; Any interest?

 Hi folks.  Is anyone interest in attending a bigtop meetup either in
 connecticut or massachusets to coincide with the one Kons is planning in
 california?

 Im sure some folks around here are using bigtop either for testing or
 development... maybe in the new york or boston areas?

 im in hartford so either location is valid for me... connecticut also would
 work (of course) as its central to both. :)

Would be really nice to see an East Coast Bigtop meetup.

In general, for all the remote folks -- we typically do have quite
a lively IRC presence on #bigtop during our meetups/hackathons.
It is not quite as being in the same room, but way better than
nothing.

Thanks,
Roman.
