FromDelimitConverter Missing from SVN
GoogleCodeExporter opened this issue · comments
Hi there, I am new to JAQL, but I involving it in an academic paper. I am
wanting to understand JAQL further to be able to draw some results. So, the
Hadoop cluster I am using is version 0.20.1 .
I have had to take a snapshot from JAQL SVN because the most recent stable
version does not support 0.20.1 . I am trying to read in a delimited file
from HDFS, but looking at your IO tutorial on the wiki, that it uses
com.acme.extensions.data.FromDelimitConverter . However, looking at the
source in SVN, this class is now missing.
Can you tell me where I am likely to find it, or better still, outline a
new process (if applicable) to parse delimited HDFS files in JAQL.
(delimited by a given format, and a new record on each line).
Thanks,
Rob Stewart

Yes, reading delimited files has been made significantly easier in the trunk.
Check
out src/test/com/ibm/jaql/storageTextQueries.txt for examples. In the case of
CSV
files, issuing read(del("filename")) is sufficient.
Note that there are two Google groups related to Jaql: jaql-user and
jaql-devel. You
can find links to them on the right-hand side of the "project home" tab.
