Subject can i use hdfs in this scenery ?
Date Tue, 13 Sep 2011 03:34:00 GMT

Hi Todd Lipcon:I am developing a log structure -like filesystem on hdfs . I hope data will
not be lost when machine that client on hanppen to crash, so I hope to flush operation log
to hdfs as soon as possible for roll forword when back from crash. However , operation log
is small , So I flush it very frequently 。 I use hflush methodfor above scenery ?  It is
resonable?    and Can I use hdfsAvailable method(or others) to get file lenght that I hflush
to but not close ? 
kanghuaThansk you
