---------------------------------
Summary: FSEditLog preallocate() needs to reset the position of
PREALLOCATE_BUFFER when more than 1MB size is needed
Key: HADOOP-8831
URL: https://issues.apache.org/jira/browse/HADOOP-8831
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 1.2.0
Reporter: Jing Zhao
Priority: Critical
In the new preallocate() function, when the required size is larger 1MB, we
need to reset the position for PREALLOCATION_BUFFER every time when we have
allocated 1MB. Otherwise seems only 1MB can be allocated even if need is larger
than 1MB.
