[jira] Commented: (PIG-824) SQL interface for Pig
[ https://issues.apache.org/jira/browse/PIG-824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=12715853#action_12715853 ] eric baldeschwieler commented on PIG-824: - Hi Jeff, Reasonable parties can clearly disagree on approach. We've been planning this approach since before Hive's inception, as we discussed before Hive's inception. Your team chose to explore an alternative approach rather than implement a SQL parser of Pig. The Hadoop community is richer for that. Having looked at the cost benefit for our organization, we've concluded that we still believe that having a single set of tools that supports Pig and SQL syntax will reduce the overall cost of running the diverse workloads we support and we are willing to invest to get to that saving. I believe the Hadoop community will be richer for having that alternative too. Let's keep talking! E14 SQL interface for Pig - Key: PIG-824 URL: https://issues.apache.org/jira/browse/PIG-824 Project: Pig Issue Type: New Feature Reporter: Olga Natkovich In the last 18 month PigLatin has gained significant popularity within the open source community. Many users like its data flow model, its rich type system and its ability to work with any data available on HDFS or outside. We have also heard from many users that having Pig speak SQL would bring many more users. Having a single system that exports multiple interfaces is a big advantage as it guarantees consistent semantics, custom code reuse, and reduces the amount of maintenance. This is especially relevant for project where using both interfaces for different parts of the system is relevant. For instance, in a data warehousing system, you would have ETL component that brings data into the warehouse and a component that analyzes the data and produces reports. PigLatin is uniquely suited for ETL processing while SQL might be a better fit for report generation. To start, it would make sense to implement a subset of SQL92 standard and to be as much as possible standard compliant. This would include all the standard constructs: select, from, where, group-by + having, order by, limit, join (inner + outer). Several extensions such as support for pig's UDFs and possibly streaming, multiquery and support for pig's complex types would be helpful. This work is dependent on metadata support outlined in https://issues.apache.org/jira/browse/PIG-823 -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.

[jira] Commented: (PIG-564) Parameter Substitution using -param option does not seem to work when parameters contain special characters such as +,=,-,?,'

Olga Natkovich commented on PIG-564:
Thanks, Giri. I looked at warnings anf they are result of adding new test files
for parameter substitution that don't have apache license because they don't
support comments. So nothing to fix there.
I will be committing the patch later today.
Parameter Substitution using -param option does not seem to work when
parameters contain special characters such as +,=,-,?,'

Key: PIG-564
URL: https://issues.apache.org/jira/browse/PIG-564
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.2.0
Reporter: Viraj Bhat
Assignee: Olga Natkovich
Attachments: PIG-564.patch
Consider the following Pig script which uses parameter substitution
{code}
%default qual '/user/viraj'
%default mydir 'mydir_myextraqual'
VISIT_LOGS = load '$qual/$mydir' as (a,b,c);
dump VISIT_LOGS;
{code}
If you run the script as:
==
java -cp pig.jar:${HADOOP_HOME}/conf/ -Dhod.server='' org.apache.pig.Main
-param mydir=mydir-myextraqual mypigparamsub.pig
==
You get the following error:

Also tried using: -param mydir='mydir\-myextraqual'
This behavior occurs if the parameter value contains characters such as +,=,
?.
A workaround for this behavior is using a param_file which contains
param_name=param_value on each line, with the param_value enclosed by
quotes. For example:
mydir='mydir-myextraqual' and then running the pig script as:
java -cp pig.jar:${HADOOP_HOME}/conf/ -Dhod.server='' org.apache.pig.Main
-param_file myparamfile mypigparamsub.pig
The following issues need to be fixed:
1) In -param option if parameter value contains special characters, it is
truncated
2) In param_file, if param_value contains a special characters, it should be
enclosed in quotes
3) If 2 is a known issue then it should be documented in
http://wiki.apache.org/pig/ParameterSubstitution
