Subject Re: Cant load coprocessor
Date Sat, 20 May 2017 18:51:10 GMT
Has anyone successfully tried to load a coprocessor from hbase shell in
hbase 1.2.5 with "*alter 'TABLE', 'coprocessor' =>
'hdfs://9c0def24f75:9000/hbase/lib/myJar.jar|org.apache.hadoop.hbase.mypackage.MyCoprocessor|805306366|'
*"?

Regards,

Cheyenne O. Forbes
