hi,everyone!
when I test Hadoop-vertica-connect,I had some wrong.

Code: Select all

[root@h05 hadoop]# hadoop jar hadoop-vertica-example.jar \
>  com.vertica.hadoop.VerticaExample \
>  -Dmapred.vertica.hostnames=h02,h03,h04,h05 \
>  -Dmapred.vertica.port=5433 \
>  -Dmapred.vertica.username=dbadmin \
>  -Dmapred.vertica.password=test \
>  -Dmapred.vertica.database=test

Hi,

Do you want to create a new resource pool or just alter a user's resource pool?
