Glutshowwindow makes the current window visible (it may still be blocked by other windows).
Gluthidewindow makes the current window non-visual.
Gluticonifywindow makes the current window an icon, which is also minimized.

Write availability in case of failure
Read and write consistency across data centers
We are delighted to see that the HBase community has begun to address these issues and is trying to merge the Facebook-developed hydrabase into HBase. In the future, HBase will provide up to 5 9 (or 99.999%) availability while ensuring that critical business systems have strong data consistency requirements.Or
