I have installed hadoop-0.19.2 on my system and I am using Hive to

When you¹re doing a select *, you¹re not using a Map/Reduce, just reading
data directly
Select some column will try to create a new directory on HDFS and will fail
because of safe mode.
Wait for your HDFS to no longer be on safe mode: Name node is in safe mode.

Hello,
I was trying the following in the Cloudera training vm 0.3.2 (hadoop 0.20):
I'm parsing a syslog file with RegexSerDe. I created the table thus:
CREATE TABLE syslog (month STRING, day STRING, time STRING, host STRING,
logline STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde
Has anyone seen a TransactionNotWritableException during a LOAD DATA
command? We get it very sporadically - I'd say one out of every couple
hundred loads - and if you rerun the same query, it runs fine. We're using
Hive trunk r819727, and MySQL directly as the metastore. Log below.
Thanks!
