[jira] [Updated] (PIG-3207) Pig fails with horrible and untraceable
error when semi-colon is inside a comment that splits a statement
[ https://issues.apache.org/jira/browse/PIG-3207?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sal Uryasev updated PIG-3207:
-----------------------------
Description:
If a semi-colon is included in a comment that splits a GENERATE statement, Pig fails with either this error:
ERROR 1200: <line 0, column -1> Syntax error, unexpected symbol at or near 'null'
or just:
ERROR 1200: null
This error does not happen if the comment does not split a statement. I did not test this with non-GENERATE statements.
This happens both in grunt and when running a pig script from a file, though it is primarily an issue with the file.
Grunt example:
grunt> m = LOAD '/user/suryasev/fips2.txt' USING PigStorage('\t');
grunt> n = FOREACH m GENERATE $4 as first_item, $5 as second_item;
grunt> describe n;
n: {first_item: bytearray,second_item: bytearray}
grunt> k = FOREACH n GENERATE first_item, --some comment;
2013-02-22 00:19:29,974 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 0, column -1> Syntax error, unexpected symbol at or near 'null'

This happens both in grunt and when running a pig script from a file, though it obviously is way more frustrating with the file. It is always baffling when deleting a comment makes the code work.

grunt> m = LOAD '/user/suryasev/fips2.txt' USING PigStorage('\t');
grunt> n = FOREACH m GENERATE $4 as first_item, $5 as second_item;

n: {first_item: bytearray,second_item: bytearray}
