Oliver Bucaojit updated TRAFODION-2449:
---------------------------------------
Attachment: TRAFODION-2449.v2.patch
Uploading v2 patch.
Worked around single region issue by instead passing one long string with all
the region information and delimiting with a '|'. The RegionInfo string is
then parsed in dtmci.
Fixed a few bugs in existing code to get this working:
- Changed transid type to long
- Different data structure in HashMapArray -- HashMap<Long, String> vs
ArrayList<HashMap<String, String>>();
- Keeps track of transid from C++ to Java in order to correlate transid with
regions
- Fixed iteration over the TransactionRegionLocation in HBaseTxClient
Current version prints the full region name, hostname:port, and
startkey/endkeys in hex format.
Example:
$ dtmci
DTM Command line interface. v 3.1.0, Nov 26, 2014
DTMCI > status regions

> Project: Apache Trafodion
> Issue Type: Improvement
> Components: dtm

> Request for enhancement
> dtmci 'status trans' does not show information regarding table name,
> regionserver, or region. It would be beneficial for troubleshooting and
> understanding the path taken by a transaction to include HBase related
> information.
> Initial idea would be to add a 'detailed' option to specifying the trans id.
> DTMCI > status trans <transid>, detailed
> Looking at the code, this work would require adding JNI calls from the tm
> process to the HBaseTxClient class to gather this information.
