Hi
I performed this testing on 2 node cluster where its i7 core processor with
16 gb ram 8 core on each node.
I have very frequent get put operation on hbase using spark streaming and
sql where we r aggregate data on spark group and saving it to hbase
Can you give us more specifics about what kind
Can you give us more specifics about what kind of performance you're
expecting, Manjeet, and what kind of performance you're actually seeing?
Also, how big is your cluster (i.e. number of nodes, amount of RAM/CPU per
node)? It's also important realize that performance can be impacted by the

Thanks Vladrodionov for your reply
I took this design from twiter where a rowkey is twitter id and twites and
hastag in column
I hv mob no or ip by which domain visited in column qualifyer.
can you plz tell me how can I index my row key with qualam idk how many
column I hv

rows are not indexed by column qualifier, and you need to scan all of them.
I suggest you consider different row-key design or
add additional index-table for your table.

Hi All,
can anybody suggest me the improvement in my below code
Purpose os this code to get column qualifier by prefix scan
Problem is its very slow
public static ArrayList getColumnQualifyerByPrefixScan(String
rowKey, String prefix) {
ArrayList list = null;
try {
FilterList filterList = new F
Looks like the image didn't go through.
Can you pastebin the error ?
Cheers

Hi All
I am using wide table approach where I have might have more 1,00,
column qualifier
I am getting problem as below
Heap size problem by using scan on shell , as a solution I increase java
heap size by using cloudera manager to 4 GB
second I have below Native API code It took very long
That is true.
Mind telling us more about your setup?I think that would be interesting
knowledge.

I meant controlling compaction activity by emitting fewer hfiles but of
larger size.

You'll need more memory then, or more machines with not much disk attached.

That way you can reduce that ratio to 1/200 or even less.

Hi,
I was wondering how much folks typical give to hbase and how much they
leave for the file system cache for the region server. I am using hbase
0.94 and running only the region server and data node daemons. I have a
system with 15G ram.
Thanks

Concurrent GC (a.k.a CMS) does not mean that there is no more pause. The
pauses are reduced to minimum but can still happen especially if the
concurrent thread will not finish their work under high pressure. The G1
collector in JDK 7.0 pretends to be a better collector than CMS, but i

Oleg:
Instead of setting the heap size using the common HBASE_HEAP_SIZE, use
the process specific OPTS to set it.
As Stack says, for instance to set zookeeper specific heap size, you
can uncomment and set the heap size
export HBASE_ZOOKEEPER_OPTS="-Xmx1000m $HBASE_JMX_BASE
-Dcom.sun.management.jmx
Thank you St.Ack
the question is regarding setting heap size for hbase:
As I understand there are 3 processes HBASE master , Hbase Region server ,
Zookeper.
What is the heap size should I set for these processes? I don't remember
where do I see 4000m was recommended , but does it mean that all
See this section in your hbase-env.sh:
# export HBASE_JMX_BASE="-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
# export HBASE_MASTER_OPTS="$HBASE_JMX_BASE
-Dcom.sun.management.jmxremote.port=10101
-javaagent:lib/HelloWorldAgent.jar"
# export HBASE_REGIO
Hi , we started our tests on cluster ( hbase 0.90.1 , hadoop append) ,
I set HBASE_HEAPSIZE to 4000m in hbase-env.sh and got 3 processes which
has heap size 4000m:
my questions are:
1)What is the way to set separately heap size for these processes. In case
I want to give to zookeper less h
