a separate compression type field is unnecessary and error-prone as it has been 
captured in compressionFinder abstraction.

[jira] [Created] (CARBONDATA-607) Cleanup ValueCompressionHolder class and all sub-classes

 Summary: Cleanup ValueCompressionHolder class and all sub-classes
 Key: CARBONDATA-607
 URL: https://issues.apache.org/jira/browse/CARBONDATA-607
 Project: CarbonData
  Issue Type: Improvement
  Components: core
Reporter: Jihong MA
Assignee: Jihong MA


Rewrite ValueCompressionHolder class as a base class for compressing or 
uncompressing numeric data for measurement column chunk. 

refactored all sub-classes under
org.apache.carbondata.core.datastorage.store.compression.decimal.*
org.apache.carbondata.core.datastorage.store.compression.nonDecimal.*
org.apache.carbondata.core.datastorage.store.compression.none.*
org.apache.carbondata.core.datastorage.store.compression.type.*

as part of the work, also fixed a performance bug to avoid creating unnecessary 
compression/uncompression value holder during compression or decompression.

[jira] [Commented] (CARBONDATA-11) Support carbon spark sql cli and carbon spark shell in carbondata to simplify operations for first time users

2016-06-27 Thread Jihong MA (JIRA)

Jihong MA commented on CARBONDATA-11:
-

let's incorporate this work with CarbonContext refinement, so the ultimate goal 
is to consolidate it ( including metadata management)  into SqlContext without 
a need for a special CarbonContext for Carbondata table.

> Currently in carbon there is no support spark sql cli. And also there is no 
> dedicated carbon shell in carbon so for first time users to use carbon is no 
> so easy. These two features simplify operations for first time users and have 
> good experience.
