HTable object - how long it is valid

[Venkatesh <vr...@aol.com>]

 Hi

If I construct new HTable() object upon my app init, is it valid until my app is shutdown?
I read in earlier postings that it is better to construct HTable once for performance reasons.
Wonder if underlying connection & other resources are kept around for ever for put/scan/..

Also ..when do I call close()..upon every operation (put/get/..) ? to avoid memory leaks

thanks

A HTable doesn't contain any state unless you use the write buffer.
close() only flushes the write buffer. The only thing you need to be
sure of is to close your scanners (they have a timeout on the region
server if you stop using them, but better be clean).
