Finally I fix it .
It just cause by "ClassNotFoundException: org.apache.htrace.Trace".
I can't see this message in logs on driver node,but can be found on worker node.
And I modify "spark.executor.extraClassPath" in spark-default.conf still not
work.Also modify classpath.txt on every node.
It can work use spark-submit options "--driver-java-options
-Dspark.executor.extraClassPath=/opt/cloudera/parcels/CDH/jars/htrace-core-3.1.0-incubating.jar"
Thanks.

Can you pastebin log snippet showing hbase related errors ?
Please also consider posting the question on vendor's forum.

I add hbase-conf-dir to spark/conf/classpath.txt,but still error.

The second code snippet is similar to:
examples//src/main/scala/org/apache/spark/examples/HBaseTest.scala
See the comment in HBaseTest.scala :
// please ensure HBASE_CONF_DIR is on classpath of spark driver
// e.g: set it through spark.driver.extraClassPath property
// in spark-defaults.conf or through --driver-class-path
// command line option of spark-submit
If during execution of TableInputFormatBase#initializeTable(), there was
exception, table field might not have been initialized.
FYI

I have try this
SparkConf sparkConf = new SparkConf().setAppName("HBaseIntoSpark");
JavaSparkContext sc = new JavaSparkContext(sparkConf);
Configuration conf = HBaseConfiguration.create();
Scan scan = new Scan();
scan.addFamily(Bytes.toBytes("InnerCode"));
scan.addColumn(Bytes.toBytes("InnerCode"), Bytes.toBytes(""));
conf.set(TableInputFormat.INPUT_TABLE, "SecuMain");
conf.set(TableInputFormat.SCAN, convertScanToString(scan));
and this
SparkConf sparkConf = new SparkConf().setAppName("HBaseIntoSpark");
JavaSparkContext sc = new JavaSparkContext(sparkConf);
Configuration conf = HBaseConfiguration.create();
String tableName = "SecuMain";
conf.set(TableInputFormat.INPUT_TABLE, tableName);
also can't wok!
Should I add hbase-site.xml to conf?
Thanks.

One possibility was that hbase config, including hbase.zookeeper.quorum, was
not passed to your job.
hbase-site.xml should be on the classpath.
Can you show snippet of your code ?
Looks like you were running against hbase 1.x
Cheers

Does anyone know how does this happen?
