Hi, cool - thanks, it works nicely - taking this even further. Is there a
way to get only the "plain text" region name - for instance, doing a plain
scan results in something like:
my_table,\xA0\x03\x93\xC7\x81aBb\x8Cr\x1D\xB0\x93\x9D\x
column=info:regioninfo, timestamp=1398333985425, value={NAME =>
'my_table,\xA0\x03\x93\xC7\x81aBb\x8Cr\x1D\xB0\x93\x9D\xBC\x0E,1392713217395.09326af68a5973257f8d88155
BC\x0E,1392713217395.09326af68a5973257f8d881552f809cd. 2f809cd.',
STARTKEY => '\xA0\x03\x93\xC7\x81aBb\x8Cr\x1D\xB0\x93\x9D\xBC\x0E', ENDKEY
=> '\xBF\xB9\x92\xA4N\x11C\x8E\x9A$a\xEF\xB2\xB7R\xC6', ENCODED =>
09326af68a5973
257f8d881552f809cd,}
and all I require is "09326af68a5973257f8d881552f809cd" - which I believe
is the HFile name. I currently extract this using some ugly stuff on the
command line on the hbase shell output.
Thanks,
/David
