HRegionserver daemon is not running on region server node
hi
i am working with 2 node hbase cluster as shown below
On node1 (10.0.1.54) : master node, region server, hadoop namenode, hadoop
datanode
on node2 (10.0.1.55): region server, hadoop datanode.
When i start both hadoop then hbase, all daemons are running properly on
masternode i.e node1,
2404 NameNode
3657
3007 TaskTracker
2848 JobTracker
3522 HRegionServer
3848 Main
3292 HQuorumPeer
2769 SecondaryNameNode
3345 HMaster
2575 DataNode
4768 Jps
but on node2, only TaskTracker and Datanode daemons are running, the
HRegionServer daemon is not running.
I provide some files which may be helpful in helping me. i have my
/etc/hosts file of node1 (vamshikrishna-desktop) has
# /etc/hosts (for master AND slave)
127.0.0.1 localhost
127.0.1.1 vamshikrishna-desktop
10.0.1.54 hbase-master hadoop-namenode
10.0.1.55 hbase-regionserver1 hadoop-datanode1
and file {HBASE_HOME}/conf/regionservers has
hbase-regionserver1
hbase-master
i have my /etc/hosts file of node2 (vamshikrishna-laptop) has
127.0.0.1 localhost
127.0.0.1 vamshi-laptop
10.0.1.54 hbase-master hadoop-namenode
10.0.1.55 hbase-regionserver1 hadoop-datanode1
and file {HBASE_HOME}/conf/regionservers has
localhost
Please can anybody help me in finding out what is the reason for
Regionserver not running on node2..? And moreover when i run
start-hbase.sh , it will display error like
hbase-regionserver1: bash: line 0: cd: {HBASE_HOME}/bin/..: No such file or
directory
hbase-regionserver1: bash: {HBASE_HOME}/bin/hbase-daemon.sh: No such file
or directory , but i could find out {HBASE_HOME}/bin/hbase-daemon.sh
clearly.. i don't know what went wrong..!
please can any body help?

Vamshi:
What OS are you trying this on? Is it Linux / Windows?
You can use the *.dns.interface configurations to use the specific
network interface that you want.
That is, set the following configurations in your hbase-site.xml on
all hbase nodes
hbase.zookeeper.dns.interface
hbase.regionserver.dns.interface
hbase.master.dns.interface
You can set it to lo or eth0 or eth1 per your environment.
Restart all nodes after this and you should see them bind to the
specified interface.
You can do the same for hadoop by setting dfs.datanode.dns.interface
in hdfs-site.xml for hadoop nodes.
On Windows cygwin, I've found setting that it to "localhost" works.
Your setup should work for test environments ... for production, the
standard setup would be to co-locate region servers and data nodes to
get data locality.

Re: HRegionserver daemon is not running on region server node
Posted by Vamshi Krishna <va...@gmail.com>.
Thankyou suraj, beacuase of discussing on that issue with you, i came to
know many other things also which i need to take care of during hbase
setup. Finally that problem i mentioned got resolved i.e now i can see the
following after i run bin/start-hbase.sh on my master machine,
hbase-master: starting zookeeper, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-zookeeper-vamshikrishna-desktop.out
starting master, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/logs/hbase-hduser-master-vamshikrishna-desktop.out
hbase-regionserver2: starting regionserver, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-arun-desktop.out
hbase-regionserver1: starting regionserver, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-vamshi-laptop.out
hbase-master: starting regionserver, logging to
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-vamshikrishna-desktop.out
But still , if i do jps on both region server machines, HRegionServer
daemon is not seen.And i checked the logs on both the regionservere
machines, i.e
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-vamshi-laptop.log
---(hbase-regionserver1)
and
/home/hduser/Documents/HBASE_SOFTWARE/hbase-0.90.4/bin/../logs/hbase-hduser-regionserver-arun-desktop.log
---(hbase-regionserver2)
i found the same in both .it is like this, (here vamshikrishna-desktop is
the master and namenode machine)

Re: HRegionserver daemon is not running on region server node
Posted by Suraj Varma <sv...@gmail.com>.
Ok.
Can you run dos2unix against both your HBASE_HOME/bin and
HBASE_HOME/conf directory?
After this, restart your cluster and see if you are getting the same issue.

Re: HRegionserver daemon is not running on region server node
Posted by Vamshi Krishna <va...@gmail.com>.
Hi,
1)No, hbase is running as same user i.e hduser, in all machines i have
hbase in hduser account only.
2)Yes, iset HBASE_HOME environmental variable in all machines under hduser
, in the file /.bashrc like
export HBASE_HOME=/home/hduser/Documents/HBASE_SOFTWRAE/hbase-0.90.4
And, in all the machines, hbase is located at the same place, i.e if i run
command echo $HBASE_HOME in all machines separatley ,under hduser
account, three machines are printing
/home/hduser/Documents/HBASE_SOFTWRAE/hbase-0.90.4 , So, i hope
HBASE_HOME is set in all machines, right?
3) i didn't understand " If a new bash env is created, will that env get
inherited?" statement. I didn't create any new bash env.
4) i changed all the machines to wired network only. Now all machines are
connected with wired connection.
5)hbase is running fine in standalone mode.
Hadoop is running all machines perfectly, i ran some example(word count) ,
its running fine on all machines, in distributed mode.
Hbase is perfectly running on master node ONLY.
This is my present situation, i am feeling like just struck with this
problem, please help.

Re: HRegionserver daemon is not running on region server node
Posted by Suraj Varma <sv...@gmail.com>.
So - first of all:
> hbase-regionserver2: bash: line 0: cd: {HBASE_HOME}/bin/..:
> No such file or
> directory
This indicates that the environment of the process running
hbase-regionserver2 is not set correctly. It is not able to find the
directory.
Is hbase running as a different user?
I think your first step should be to get the above "No such file or
directory" errors resolved. Did you set HBASE_HOME in the environment
manually? If a new bash env is created, will that env get inherited?
So - start simple steps first - get hbase running stand alone, then
move to pseudo / fully distributed.
By introducing variables like wired/wireless etc in your network, you
are introducing uncertainities which will bite you on an ongoing basis
(wireless going down, increased latencies, etc, etc). So - the cluster
is unlikely to be stable with such a setup.
I would recommend going with a fully wired setup, if your goal is to
have a stable hbase cluster. If it is a "at home test cluster", then
that's fine - but be prepared for frequent cluster reboots. :)

Re: HRegionserver daemon is not running on region server node
Posted by Vamshi Krishna <va...@gmail.com>.
Hi suraj,
Thank you,
i am using ubuntu-10.04 OS. actually i am using 3 machines out of which
two are desktops connected with wired connection(10.0.1.54 and 10.0.1.97),
other is laptop(10.0.1.55) connected with wireless router. i didnot modify
any of such interface settings in hbase-site.xml file.
Would this sort of connecting nodes (i.e using both wired and wireless
connections) create any such problem as i mentioned? If so, atleast two
desktop machines are connected with same wired connection, then also it
threw an error, like
hbase-regionserver2: bash: line 0: cd: {HBASE_HOME}/bin/..: No such file or
directory
hbase-regionserver2: bash: {HBASE_HOME}/bin/hbase-daemon.sh: No such
file or directory
i will change hbase-site.xml as you have suggested and let you know what is
happening. But before that answer my above query please.
One more thing is, i am running region servers on the datanodes and
master only, then i hope it would become co-located, right?
Thank you

Re: HRegionserver daemon is not running on region server node
Posted by Suraj Varma <sv...@gmail.com>.
Vamshi:
What OS are you trying this on? Is it Linux / Windows?
You can use the *.dns.interface configurations to use the specific
network interface that you want.
That is, set the following configurations in your hbase-site.xml on
all hbase nodes
hbase.zookeeper.dns.interface
hbase.regionserver.dns.interface
hbase.master.dns.interface
You can set it to lo or eth0 or eth1 per your environment.
Restart all nodes after this and you should see them bind to the
specified interface.
You can do the same for hadoop by setting dfs.datanode.dns.interface
in hdfs-site.xml for hadoop nodes.
On Windows cygwin, I've found setting that it to "localhost" works.
Your setup should work for test environments ... for production, the
standard setup would be to co-locate region servers and data nodes to
get data locality.

Re: HRegionserver daemon is not running on region server node
Posted by Vamshi Krishna <va...@gmail.com>.
Hi, i checked by executing netstat -anp, i found
tcp 0 0 127.0.1.1:60000 0.0.0.0:*
LISTEN 6814/java
.
***some other ports**
tcp 0 0 0.0.0.0:60010 0.0.0.0:*
LISTEN 6814/java .
***some other ports**
.
tcp 0 0 10.0.1.54:44095 10.0.1.54:9000
ESTABLISHED 6814/java
***some other ports**
tcp 0 0 10.0.1.54:55204 10.0.1.54:2222
ESTABLISHED 6814/java
***some other ports**
***some other ports**
the port of HMaster i found when i ran jps is 6814. But the same port i
found in different places bound to different IPs (i.e some time 127.0.1.1 ,
and some times 10.0.1.54). Same is the case with all other daemons which
are running after i ran bin/start-hbase.sh
Does it cause any abnormal behavior if i have like above. All hadoop
daemons are runnong on other machines, but hbase daemon i.e HRegionServer
is not running on other machines. HMaster, HQuorumPeer, HRegionServer are
running on master node.
My /etc/hosts file has content like
127.0.0.1 localhost
127.0.1.1 vamshikrishna-desktop
10.0.1.54 hbase-master hadoop-namenode
10.0.1.55 hbase-regionserver1 hadoop-datanode1
Still what more modification i need to do to bind the hostnames to IPs?
Please some body help..

Re: HRegionserver daemon is not running on region server node
Posted by Joey Echeverria <jo...@cloudera.com>.
I suspect that the daemon's are binding to 127.0.0.1 instead of
10.0.1.54 on the master. You can check this by running netstat -anp. I
would recommend either configuring the /etc/hosts to bind the
vamshikrishna-desktop and vamshi-laptop hostnames to the 10.0.1.x
addresses.
