*环境配置如下：*
hbase-1.4.13
flink-1.11.1
python-3.6.1
pyflink-1.0
*已做配置如下：*
1.hadoop classpath下已经加入hbase路径 （:/opt/hbase/hbase-1.4.13/lib/*）
2.程序ddl配置如下：
source_ddl = """CREATE TABLE MySourceTable (
hbase_rowkey_name varchar, cf1 ROW<word varchar>) WITH (
'connector.type' = 'hbase',
'connector.version' = '1.4.3',
'connector.table-name' = 'flink-test',
'connector.zookeeper.quorum' =
'es-zk-hadoop1:2181,es-zk-hadoop2:2181,es-zk-hadoop3:2181',
'connector.zookeeper.znode.parent' = '/hbase')
"""
sink_ddl = """CREATE TABLE MySinkTable (
hbase_rowkey_name varchar, cf1 ROW<cnt bigint>) WITH (
'connector.type' = 'hbase',
'connector.version' = '1.4.3',
'connector.table-name' = 'flink-test-result',
'connector.zookeeper.quorum' =
'es-zk-hadoop1:2181,es-zk-hadoop2:2181,es-zk-hadoop3:2181',
'connector.zookeeper.znode.parent' = '/hbase')
"""
3.zookeeper无鉴权
4.hive能关联访问hbase
5.hbase shell命令能正确执行
6.hbase 集群状态正常
7.hbase lib目录下jar包如下：
./hbase-common-1.4.3.jar
./flink-connector-hbase_2.11-1.11.1.jar
./hbase-client-1.4.3.jar
./hbase-protocol-1.4.3.jar
*出错信息如下:*
