Aaron T. Myers commented on HDFS-3541:
--------------------------------------
Patch looks pretty good to me. Just two small comments:
# Misspelled "interrupted": "Finalizing block from Inturrupted thread should
fail"
# This chunk of code confuses me, since you don't use {{written}} again after
the loop, and there doesn't seem to be any need to call {{write(...)}} many
times:
{code}
+ int written = 0;
+ for (; written < 512;) {
+ out.writeBytes(data);
+ written += 4;
+ }
{code}
Kihwal, how does this patch look to you?
