Ok, get_multi_table definitely sounds better. > On 2011-06-03 14:04:02, Ashutosh Chauhan wrote: > > trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java, > > line 521 > > <https://reviews.apache.org/r/831/diff/1/?file=20145#file20145line521> > > > > You can write this more concisely using commons-lang utility method as: > > StringUtils.join(tbls,','); Thanks for the tip; I changed this. > On 2011-06-03 14:04:02, Ashutosh Chauhan wrote: > > trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java, > > line 1182 > > <https://reviews.apache.org/r/831/diff/1/?file=20145#file20145line1182> > > > > You can get rid of tables.get(i) == null check that will never be true. I cleaned up the checks for seeing if the db had all the requested tables. Also, I realized that I did not guarantee returning tables in the same order as those requested, so I fixed that up too. > On 2011-06-03 14:04:02, Ashutosh Chauhan wrote: > > trunk/metastore/src/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java, > > line 1195 > > <https://reviews.apache.org/r/831/diff/1/?file=20145#file20145line1195> > > > > Instead of throwing RuntimeException, create MetaException and throw > > that. I changed it to throw a MetaException instead. However, the other metastore operations (e.g., get_table, append_partition) throw RuntimException, which is what I based get_multi_table off. > On 2011-06-03 14:04:02, Ashutosh Chauhan wrote: > > trunk/service/src/test/org/apache/hadoop/hive/service/TestHiveServer.java, > > line 221 > > <https://reviews.apache.org/r/831/diff/1/?file=20148#file20148line221> > > > > This test really belongs in the TestMetastore or some such in metastore > > dir not in HiveServer.
