Subject [jira] [Commented] (PIG-2482) Integrate HCat DDL command into Pig
Date Sat, 28 Jan 2012 00:21:11 GMT

    [ https://issues.apache.org/jira/browse/PIG-2482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13195271#comment-13195271

Alan Gates commented on PIG-2482:

In general looks good.  A couple of comments/questions:

In GruntParser.processSQLCommand(), the error message in the following code looks incomplete:


if (new File("hcat.bin").exists()) {
    throw new IOException(hcatBin + " does not ");

How does removing HADOOP_CLASSPATH from the environment variable solve the problem of antlr
version clashes?  Doesn't hcat need HADOOP_CLASSPATH set in order to work properly?

> We would like to run hcat DDL command inside Pig script or Grunt. We can use a similar
approach as "fs" or "sh".

> Similar to "fs" and "sh", we don't plan to add Java API in PigServer for it.
