Dec 05, 2009 issue 73 (FromDelimitConverter Missing from SVN) reported by robstewart57 - 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 Hi there, I am new to JAQL, but I involving it in an academic paper.

Nov 18, 2009 issue 71 (Simplify schema and add annotations) reported by Rainer.G...@gmx.de - Evaluation of the current implementation of schema has shown that some of the information in the schema is too detailed: its usefulness is limited but its propagation through the expression tree is complex. This includes: - min length / max length information of (binary) strings and arrays - min value / max value information of all ordered types - regex patterns for strings These features will be removed. Then, each schema type has the following modifiers: - value (existing): mainly used to propagate compile-time constants - annotation (new): arbitrary user-defined information about the schema The main purpose of annotations is to pass schema information directly to a serialization routine (e.g., to customize serialization or facilitate pretty printing). No guarantees are made about the propagation of annotations through the query tree; they are meant to be used for schemata that are passed as arguments or stored in a value.
