首先查到了需要调整参数 base.client.scanner.timeout.period，项目使用shc 不是外部维护的conf，配置如何加是个问题

方式1  改本地配置，找到两个可能的配置文件
/opt/hbase/conf/hbase-site.xml
/opt/hadoop/etc/hadoop/hbase-site.xml

添加

<property>
<name>hbase.client.scanner.timeout.period</name>
<value>36100000</value>
</property>

提交，问题依旧

方式2 官方 readme.md 有相关的示例

https://github.com/hortonworks-spark/shc

./bin/spark-submit --class your.application.class --master yarn-client --packages com.hortonworks:shc-core:1.1.-2.1-s_2. --repositories http://repo.hortonworks.com/content/groups/public/ --jars /usr/hdp/current/phoenix-client/phoenix-server.jar --files /etc/hbase/conf/hbase-site.xml /To/your/application/jar

主要看到提交了  --files /etc/hbase/conf/hbase-site.xml  文件

更改本地 hbase-site.xml 添加

<property>
<name>hbase.client.scanner.timeout.period</name>
<value>36100000</value>
</property>

后 spark-submit --files /etc/hbase/conf/hbase-site.xml

线上任务失败报错，任务无法执行，猜测是线上本身有hbase-site.xml和本地的hbase-site.xml 不一致,提交本地hbase-site.xml文件，覆盖了原本正常的配置，导致异常

可以找hbase的维护方，要一个完整的线上配置文件，再添加hbase.client.scanner.timeout.period 项后提交。

方式3 在没有线上原始hbase-site.xml的情况下，试试提交hbase-default.xml

新建文件 hbase-default.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.client.scanner.timeout.period</name>
<value>3620000</value>
</property>
</configuration>

后 spark-submit --files /etc/hbase/conf/hbase-default.xml

报错
20/02/27 22:53:40 INFO SparkContext: Successfully stopped SparkContext
20/02/27 22:53:40 INFO ApplicationMaster: Unregistering ApplicationMaster with FAILED (diag message: User class threw exception: java.lang.RuntimeException: hbase-default.xml file seems to be for an older version of H
Base (null), this version is 1.2.2
at org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(HBaseConfiguration.java:71)

首先报错，原因是hbase-site.xml检查版本,hbase-default.xml版本不一致，虽然报错，不过看到希望了，有检测，表示会加载

添加项 hbase.defaults.for.version和线上hbase版本一致

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.client.scanner.timeout.period</name>
<value>3620000</value>
</property>
<property>
<name>hbase.defaults.for.version</name>
<value>1.2.2</value>
</property>
</configuration>

提交任务执行正常

但依然报错

20/02/27 19:36:22 WARN TaskSetManager: Lost task 21.0 in stage 3.0 (TID 24, 728.slave.adh, executor 63): org.apache.hadoop.hbase.client.ScannerTimeoutException: 3803499ms passed since the last invocation, timeout is currently set to 3600000

hbase-default.xml的配置根本就没有生效，比较奇怪，有检测版本的异常，则应该是加载hbase-default.xml文件，配置已经加进去了，先放下

方法4

官方

https://github.com/hortonworks-spark/shc/issues/160

There are two ways to do this:
(1) put your extra configurations in a file, and make the file as the value of HBaseRelation.HBASE_CONFIGFILE. Refer to here.

(2) put your extra configurations in json format, and make the json as the value of HBaseRelation.HBASE_CONFIGURATION.

没有指定HBaseRelation.HBASE_CONFIGFILE则用path下的配置，但上面几种改hbase-default.xml，hbase-site.xml的方式都失败了

试试  HBaseRelation.HBASE_CONFIGURATION.

相关代码 https://github.com/hortonworks-spark/shc/blob/master/core/src/main/scala/org/apache/spark/sql/execution/datasources/hbase/HBaseRelation.scala

val hBaseConfiguration = parameters.get(HBaseRelation.HBASE_CONFIGURATION).map(
parse(_).extract[Map[String, String]])

al conf = HBaseConfiguration.create
hBaseConfiguration.foreach(_.foreach(e => conf.set(e._1, e._2)))
hBaseConfigFile.foreach(e => conf.set(e._1, e._2))
conf

parse转json字符串串，再提取extract为 k:v 结构，问时是看这样子json串里的配置会被hbase-site.xml里的替换掉，不知道线上hbase-site.xml里有没有这相配置

试试

.options(Map(
HBaseTableCatalog.tableCatalog -> catalog.catalogEsDocByFields(hTable, fields),
HBaseRelation.HBASE_CONFIGURATION ->"{\"hbase.client.scanner.timeout.period\": \"3820000\"}"
))

提交任务，任务执行

20/02/28 03:35:15 ERROR Executor: Exception in task 16.1 in stage 3.0 (TID 50)
org.apache.hadoop.hbase.client.ScannerTimeoutException: 4092211ms passed since the last invocation, timeout is currently set to 3820000

3820000 虽然报错，但base.client.scanner.timeout.period这个参数是终于生效了

问题解决，补充，因为不同yarn集群path下的hbase-site.xml内容可能不同，方案并不适用全部场景
