wuchengzhi created PHOENIX-1521:
-----------------------------------
Summary: cpu 100% when using local secondary index.
Key: PHOENIX-1521
URL: https://issues.apache.org/jira/browse/PHOENIX-1521
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.2
Environment: hadoop2.5.1
hbase-0.98.7-hadoop2
phoenix-4.2.1
--------------------------------------------
8 Servers(cpu : 24 processors, RAM:64G)
16 regionservers (each server 2 regionservers)
Reporter: wuchengzhi
Priority: Critical
I run upsert test with 96 threads(each client 12 threads) to run upsert sql
together, each 2,000,000 rows, and 10000 rows batch.
ThreadPoolExecutor executor = new ThreadPoolExecutor(16, 16, 30,
TimeUnit.SECONDS, new ArrayBlockingQueue(50));
executor.submit(new Callable<Long>() {
public Long call() throws Exception {
Connection conn = null;
//....
for(int j = 0; j < 2000000; j ++ ) {
if (j > 0 && j % (10000) == 0) {
stmt.executeBatch();
conn.commit();
}
}
}
});
DDL:
create table TEST_USER (id varchar primary key , attr1 varchar, attr2
varchar,attr3 varchar,attr4 varchar,attr5 varchar,attr6 integer,attr7
integer,attr8 integer,attr9 integer,attr10 integer )
DATA_BLOCK_ENCODING='FAST_DIFF',VERSIONS=1,BLOOMFILTER='ROW',COMPRESSION='LZ4',BLOCKSIZE
= '65536',SALT_BUCKETS=16;
without the index, there are 350,000 rows per seconds putting in the hbase,and
the cpu ,memery is very low.
the i recreate the table and create one index as :
create local index TEST_USER_INDEX on
TEST_USER(attr1,attr2,attr3,attr4,attr5,attr6,attr7,attr8,attr9,attr10);
using the same client code to send request.
but i got only 85,000 rows per seconds, and the cpu is high load almost 100% in
each server.
i get the jstack info when running.
