James Taylor resolved PHOENIX-1521.
-----------------------------------
Resolution: Not a Problem
It's entirely possible that the CPU on the region server would go to 100%.
> cpu 100% when using local secondary index.

> Key: PHOENIX-1521
> URL: https://issues.apache.org/jira/browse/PHOENIX-1521
> Project: Phoenix
> Issue Type: Bug
> 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
> Assignee: rajeshbabu
>
> 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.
