猪脚本中的HIVE表中的ACID交易

Question

Is it possible to perform ACID transactions in a Hive table from a Pig script?

As per the below link we can execute DDL statements on a hive table from a pig script: https://issues.apache.org/jira/browse/PIG-2482

Answer 1

As of now only DDL command are allowed i have tested this in pig 0.16 version of HDP 2.5.3

you can create tables using hcat from PIG Grunt / Script:

override the property on the fly while executing pig script

pig -Dhcat.bin=/usr/bin/hcat test.pig

or In your pig script or Grunt shell put this in the beginning

set hcat.bin /usr/bin/hcat;

inside grunt shell or script give command like:

sql create table database_name.table_name (col1 int, col2 string);
