通过phoenix导入数据到hbase出错记录

解决方法1

错误如下

错误分析：从错误的信息来看，是关于协处理器的错误，可能是region或者表没有使用协处理器。

web界面查看表信息如下

从web信息来看，确实这张表没有相关协处理器的信息，正常通过phoenix创建表以后，都会自带phoenix相关的协处理器信息，如上面红框圈起来的地方，上图有张表(红框下面的这个)却没有，导致phoenix插入数据的时候，由于协处理器问题，导致插入失败，这种情况估计跟二级索引有一定的关系。

解决

修改表属性

# hbase shell
#####添加相关的协处理器信息
hbase(main):005:0> alter 'TABLE_RESULT', { METHOD => 'table_att','coprocessor$1' => '|org.apache.phoenix.coprocessor.ScanRegionObserver|805306366|', 'coprocessor$2' => '|org.apache.phoenix.coprocessor.UngroupedAggregateRegionObserver|805306366|', 'coprocessor$3' => '|org.apache.phoenix.coprocessor.GroupedAggregateRegionObserver|805306366|', 'coprocessor$4' => '|org.apache.phoenix.coprocessor.ServerCachingEndpointImpl|805306366|', 'coprocessor$5' => '|org.apache.phoenix.hbase.index.Indexer|805306366|org.apache.hadoop.hbase.index.codec.class=org.apache.phoenix.index.PhoenixIndexCodec,index.builder=org.apache.phoenix.index.PhoenixIndexBuilder'}

然后通过phoenix导入数据正常。

解决方法2(可能有问题)

从官网或者其他博客搜索到一些解决协处理器的问题，只是借鉴，对我这种情况不起作用

可以全局配置哪些协处理器在 HBase 启动时加载。这可以通过向 hbase-site.xml 配置文件中添加如下配置属性实现：

如下是借鉴其他人的博客：

注意：下面配置属性的值有的是他们自己Java代码实现的，所以，按如下配置加入到hbase的配置文件，在启动的时候会提示找不到相关的协处理器，导致hbase启动失败。

  <property>
        <name>hbase.coprocessor.master.classes</name>
        <value>coprocessor.MasterObserverExample</value>
    </property>
    <property>
        <name>hbase.coprocessor.regionserver.classes</name>
        <value>coprocessor.RegionServerObserverExample</value>
    </property>
    <property>
        <name>hbase.coprocessor.region.classes</name>
        <value>coprocessor.system.RegionObserverExample, coprocessor.AnotherCoprocessor</value>
    </property>
    <property>
        <name>hbase.coprocessor.user.region.classes</name>
        <value>coprocessor.user.RegionObserverExample</value>
    </property>
    <property>
        <name>hbase.coprocessor.wal.classes</name>
        <value>coprocessor.WALObserverExample, bar.foo.MyWALObserver</value>
    </property>

解决方法3

通过在hbase-site.xml文件中设置参数：

 <property>
    <name>hbase.coprocessor.abortonerror</name>
    <value>false</value>
    </property>

并启动region server可以解决，这样就忽略了协处理器出现的错误，保证集群高可用
