I have a log table with a single column, where each row contains JSON
string in the following format; here are two log entries:
{
'foo0': { 'bar0': 'A',
'bar1': 'B'}
'foo1': [ { 'params': { 'key0': 'valX', 'key1' : 'val1'},
'time': 'time0'},
After researching on the web, the lost log lines is apparently an issue with
DailyRollingFileAppender that may have been fixed in 1.2.16 (see
https://issues.apache.org/bugzilla/show_bug.cgi?id=43374).
On the other hand, DailyRollingFileAppender's documentation recommends using
RollingFileAppend
I always set it, so am not sure what the behavior is if it is not set. You
should probably always set it. See the comments/code in
CombineFileInputFormat.java for detail.

explained in the wiki :
ALTER TABLE table_name CHANGE [COLUMN] col_old_name col_new_name
column_type [COMMENT col_comment] [FIRST|AFTER column_name]

It's my bad. I was editing hive/conf/hive-log4j.properties, but turns out hive
is actually a symlink to the 0.5 tree, not 0.7. So, the properties have an
effect in 0.7 for me now.

Hey all,
Just wondering what the best way is to rename specific Hive table
partitions. Is there some HiveQL command for this, or will I need to insert
into new partitions to reflect the new naming convention?
Cheers,
Jon
