simplify the check,
if [ ! -f "$log" ] && [ -f "$log.0" ]; then #for some jdk, gc log has a suffix 0
mv -f "$log.0" "$log";

> When restarting a hbase process, hbase_rotate_log $HBASE_LOGGC will rotate GC logs.
> the code looks like this,
> if [ -f "$log" ]; then # rotate logs
> while [ $num -gt 1 ]; do
> prev=`expr $num - 1`
> [ -f "$log.$prev" ] && mv -f "$log.$prev" "$log.$num"
> num=$prev
> done
> But, some version JDK will add a postfix .0 to the gc file, like hbase-xxx.gc.0, rather than hbase-xxx.gc.
> So I add a check before rotate,
> if [ ! -f "$log" ]; then #for some jdk, gc log has a postfix 0
> if [ -f "$log.0" ]; then
> mv -f "$log.0" "$log";
> fi
> fi
