The ways that you can lose data in my point of views:
1. some tuples share the same row-key+cf+column. Hence, when you load your
data in HBase, they will be loaded into the same column and may exceed the
predefined max version.
2. As Ted mentioned, you may import some delete, do you generate tomb
How to reduce the Store File Index?Can you give me the conf filename and
parameter I need to set I am in real need. Also tell me the way to increase
hfile block size?
See 6.3.2 under http://hbase.apache.org/book.html#rowkey.design

Hi folks,
I installed hbase for my testing purpose,when i gave commands in shell mode
it shows error bunch of error code..
hbase(main):001:0> list ... ava:75) at
org.jruby.internal.runtime.methods.InterpretedMethod.call(InterpretedMethod.java:147)
at
org.jruby.internal.runtime.methods.DefaultMe
Did you install HBase in distributed mode ?
Which release do you use ?
Are you able to see tables on master UI ?
Cheers

I am using hbase to query some data in java, I also have hadoop jars in my
class path. I am able to query hbase data from main method in java class,
but calling same method from web service using Axis gives this error :
java.lang.NoClassDefFoundError:
org/apache/hadoop/hbase/filter/WritableByteArr
Looks like hbase-0.94.6-cdh4.3.0-security.jar was not in classpath.

The HBase Team is pleased to announce the immediate release of HBase 0.94.10.
Download it from your favorite Apache mirror [1]. This release has also been
pushed to Apache's maven repository.
As usual, all previous 0.92.x and 0.94.x releases can upgraded to 0.94.10 via a
rolling upgrade without

It is in class path,I also checked by unzipping the
hbase-0.94.6-cdh4.3.0-security.jar java class WritableByteArrayComparable
is present in jar. Because I have hadoop jars also I guess some jar is
conflicting with hbase jar.

Hello there,
I have an Endpoint CP which I deployed by changing the table schema using
the 'alter' command in hbase shell. I stored my CP in hdfs. My table has 4
regions, say,
region-1
region-2
region-3
region-4
Before I deployed a new CP, I use this command to remove the old CP (Do I
have to do
Sorry, I forgot to add that each region is located in a different RS.

Just make sure JAVA_HOME is set in the current shell. Also, check jps after
you start HBase.
It should indicate a process HMaster as running.

hi,all:
i am testing namenode HA,and how to config name node id? use namenode
hostname?
here nn1,nn2 is what?
dfs.ha.namenodes.mycluster
nn1,nn2
Please take a look at
http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/HDFSHighAvailabilityWithQJM.html
To my understanding, nn1 and nn2 are IDs of the NameNodes - they don't have
to be the same as namenode hostnames.

Hi All,
I'm a HBase newbie. Today I start to do stress test using 4 java process to
load large amount of rows (1 minute = 18,000 rows). After a while, one of my
region server log got this kind of WARN message:
WARN org.apache.hadoop.ipc.HBaseServer: IPC Server listener on 60020:
readAndProcess
It would be difficult for the exception to be any more explicit. Axis must
be messing w/ your classpath/class loading. Do any hbase classes load? Is
this the first? Perhaps it is the classes WBAC imports?

Hi,
I was playing around with using FuzzyRowFilter for my use case which looks
like this
rk - 18 bytes (2 bytes + 8 bytes + 8 bytes)
bytes 2-9 are fuzzy
the fuzzy mask looks like this (0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0,
0, 0, 0 ,0)
the start and stop key control the scan range
Running a sc
21 matches
