1. Can anybody suggest, why rowkey design is so important for create / retrieval of records?
2. Also, how cloudera search (SOLR) can be useful in such cases?
3. Is it mandatory to create secondary indices for retrieval?

1/ These articles describe some usefull information about rowkey and its design :
2/ If you need to query your data in HBase by a cells value .. it will be totaly inefficient. Cloudera search can help you in these cases but you will need to index the data into Cloudera search.
3/ Well, I don't have the answer to that but I would recommend you to stick to querying by the "rowkey only" if you need some "performance".
Hope this helps.

Does it mean that, I will not have to bother anymore for the Row Key design, if I use solr?
Is there any specific java code, which I need to write inorder to support it ?
I was thinking to use Apache Pheonix, if it does take care of the Row Key design internally.
Any suggestions please ?
