Stack:
- Spark 2.4.4
- Hive 2.3.3
- HBase 1.4.8
Issue: ClassCastException occurs when executing insertInto on HBase table
i’ve just read about that bug here https://issues.apache.org/jira/browse/SPARK-6628
but is there any solutions or fixes?
hive table created and mapped to hbase table with properties:
CREATE EXTERNAL TABLE hbase.h_table(
id string COMMENT '',
name string COMMENT '')
ROW FORMAT SERDE
'org.apache.hadoop.hive.hbase.HBaseSerDe'
STORED BY
'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES (
'hbase.columns.mapping'=':key,p:name',
'serialization.format'='1')
TBLPROPERTIES (
'hbase.mapred.output.outputtable'='h_table',
'hbase.table.name'='h_table',
'serialization.null.format'='NULL')
note that im unable to read table from hive atop hbase
val df = spark.sql("select * from hbase.h_table")) // that works
// hbase.h_table - hive database and table mapped to hbase table
df.write.mode("append").insertInto("hbase.h_table")

is there any solution without shc (HortonWorks spark-hbase connector)?
