Re: connecting Hbase using java
Hi all,
today I start afresh a Example code on
http://blog.rajeevsharma.in/2009/06/using-hbase-in-java-0193.html
but I guess luck is not with me.
I run
javac -classpath
~/packages/hbase-0.94.6/hbase-0.94.6.jar:~/packages/hbase-0.94.6/lib/*:~/packages/hadoop-1.1.2/*.jar:~/packages/hadoop-1.1.2/lib/*.jar
HBaseExample.java -verbose
please tell me what else I need to add in path to resolve these errors
thank you
alok@alok:~/exp/hbase/exp$ javac -classpath

I guess your hostname is alok, right?
Add a line line:
192.168.1.1 alok
in your hosts file by replacing the IP with your local IP.

Re: connecting Hbase using java
Posted by Alok Singh Mahor <al...@gmail.com>.
sorry, actually I was copy pasting code and modifying. so I missed changing
name of CF.
still I am getting some error. I tried to get something from log on google
but didnt get anything useful. I guess there is some configuration problem
in my hbase-site.xml
please look at the error at http://paste.ubuntu.com/5678610/
what is the problem at line no. 23 ?
content of /etc/hosts is
127.0.0.1 localhost
#127.0.0.1 alok
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Re: connecting Hbase using java
Posted by Jean-Marc Spaggiari <je...@spaggiari.org>.
Alok,
Can you take a deeper look in your code and your logs before asking
someone to solve that for you? ;)
Your CF is called "myColumnFamily" and not "myLittleFamily".
Also, I will recommand you to read some HBase related books where you
will learn that column familly names need to be as small as
possible... one byte is the best.

Re: connecting Hbase using java
Posted by Alok Singh Mahor <al...@gmail.com>.
yes thank you so much jean, I will switch to eclipse.
now I tried with (java -classpath `~/packages/hbase-0.94.6/bin/hbase
classpath` MyLittleHBaseClient)
code is running but I guess now I have some problem with my hbase and hadoop
I am getting output that you can see at http://paste.ubuntu.com/5676866/
could you please figure out where things are wrong now?
thanks again, your reply are helping me learning basic things.

Posted by Jean-Marc Spaggiari <je...@spaggiari.org>.

Re: connecting Hbase using java
Posted by Alok Singh Mahor <al...@gmail.com>.
wow I am not getting any error now while compiling using (javac -classpath
`~/packages/hbase-0.94.6/bin/hbase classpath` MyLittleHBaseClient.java)
but this time I am getting runtime error
alok@alok:~/exp/hbase/exp$ javac -classpath

you can see the code I am compiling at http://paste.ubuntu.com/5676812/
hadoop and hbase are running and I before running I had create table in
Hbase shell
hbase(main):001:0> create 'myTable', 'myColumnFamily'
0 row(s) in 2.3800 seconds
hbase(main):002:0> scan 'myTable'
ROW
COLUMN+CELL
0 row(s) in 0.1020 seconds

Re: connecting Hbase using java
Posted by Alok Singh Mahor <al...@gmail.com>.
thanks again JM :)
you gave very important clue.
now am trying example code in
http://hbase.apache.org/0.94/apidocs/org/apache/hadoop/hbase/client/package-summary.html#package_description
using the command
alok@alok:~/exp/hbase/exp$ javac -classpath
`~/packages/hbase-0.94.6/bin/hbase classpath` MyLittleHBaseClient.java
I am getting only one error this time. that I could not figure out. so I
still need help. please look on he error
<error>
alok@alok:~/exp/hbase/exp$ javac -classpath
`~/packages/hbase-0.94.6/bin/hbase classpath` MyLittleHBaseClient.java
MyLittleHBaseClient.java:21: error: cannot find symbol
Configuration config = HBaseConfiguration.create();
^
symbol: class Configuration
location: class MyLittleHBaseClient
1 error
</error>

Re: connecting Hbase using java
Posted by Jean-Marc Spaggiari <je...@spaggiari.org>.
Ok.
Classpath looks good.
Few points:
- org.apache.hadoop.hbase.client.Scanner doesn't exist for 0.94.6.
- org.apache.hadoop.hbase.io.BatchUpdate doesn't exist for 0.94.6.
- org.apache.hadoop.hbase.io.Cell doesn't exist for 0.94.6.
- etc.
http://hbase.apache.org/0.94/apidocs/index.html
You might want to review you source code.

thank you Harsha
with your advice I used command to compile that example code
alok@alok:~/exp/hbase/exp$ javac -classpath
`~/packages/hbase-0.94.6/bin/hbase classpath` HBaseExample.java
so errors reduced to 15 from 18
could you please what else I have to add
please see the error

Re: connecting Hbase using java
Posted by Andrea Gazzarini <an...@gmail.com>.
I don't have my laptop with me at the momemt and honestly last time I
ran a javac from command line it was about ten years ago but my
questions is : are you sure you can use wildcard this way?
If I remember well, prior to JDK 1.6 you could not use widlcards at all,
and starting from 1.6 you can use *only* wildcard, without the ".jar" suffix
Best,
Andrea
