I find the solution by google, and somebody say it maybe caused by the flush
snapshot attempting to take a region lock. See
[HBASE-7703|https://issues.apache.org/jira/browse/HBASE-7703]. But this
exception has different features.
After I flush the table, it success to create snapshot.
{code|borderStyle=solid}
hbase(main):005:0> flush 'booking'
0 row(s) in 4.5220 seconds
hbase(main):006:0> snapshot 'booking', 'booking-snapshot-20140912'
0 row(s) in 4.1270 seconds
