【问题描述】：
当我尝试使用 Hive 逻辑表将数据从 HDFS 加载到 HBase 时，我遇到了以下问题。我是 hadoop 新手，无法追踪错误，我正在使用 CDH4 VM，
创建一个由 Hive 管理的新 HBase 表
CREATE TABLE hive_hbasetable(key int, value string)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")
TBLPROPERTIES ("hbase.table.name" = "hivehbasek1");
Hbase shell 输出
hbase(main):002:0> list
TABLE
hivebasek1
mysql_cityclimate
2 row(s) in 0.2470 seconds
我在 Hive 中创建了一个逻辑表 hive_logictable
CREATE TABLE hive_logictable (foo INT, bar STRING) row format delimited fields terminated by ',';
从 HDFS 向 hive_logictable 中插入数据。
cat TextFile.txt
100,value1
101,value2
102,value3
103,value4
104,value5
105,value6
LOAD DATA LOCAL INPATH '/home/cloudera/TextFile.txt' OVERWRITE INTO TABLE hive_logictable;
使用 Hive 将数据加载到 HBase 表中。
INSERT OVERWRITE TABLE hive_hbasetable SELECT * FROM hive_logictable;
下面是抛出的错误信息......
