Affects Versions: 4.0.0
Reporter: Antal Sinkovits
Assignee: Antal Sinkovits


It can happen, that when in one given session, multiple queries are executed, 
that due to a race condition, multiple spark application master gets kicked off.
In this case, the one that started earlier, will not be killed, when the hive 
session closes, consuming resources.

[jira] [Created] (HIVE-21036) extend OpenTxnRequest with transaction type

2018-12-12 Thread Eugene Koifman (JIRA) 
Eugene Koifman created HIVE-21036:
-

 Summary: extend OpenTxnRequest with transaction type
 Key: HIVE-21036
 URL: https://issues.apache.org/jira/browse/HIVE-21036
 Project: Hive
  Issue Type: Bug
  Components: Transactions
Affects Versions: 4.0.0
Reporter: Eugene Koifman


There is a {{TXN_TYPE}} field in {{TXNS}} table.

There is {{TxnHandler.TxnType}} with legal values.  It would be useful to 
TxnType a {{Thrift}}, add a new {{COMPACTION}} type object and allow setting it 
in {{OpenTxnRequest}}.

Since HIVE-20823 compactor starts a txn and should set this.

Down the road we may want to set READ_ONLY either based on parsing of the query 
or user input which can make {{TxnHandler.commitTxn}} faster.

Perhaps add that this can run inside HMS as well.

this is also intialzied in init() - should it throw here instead?  It seems 
that the contract is that init() must be called first

What is the purpose of this?  Why doesn't the existing catch(Throwable)

Why do you need reflection for this?  Why not just do
Worker w = new Worker();, etc?



standalone-metastore/metastore-common/src/main/java/org/apache/hadoop/hive/metastore/conf/MetastoreConf.java
Lines 1020 (patched)


Perhaps this should be called hive.metastore.runworker.remotely - you can 
run 'remote' worker even with MR or 'hive.metastore.runworker.in" and support 
values "metastore" and "hs2" - this is probable more extensivble



standalone-metastore/metastore-common/src/main/thrift/hive_metastore.thrift
Lines 2448 (patched)


nit: could you move these to around line 2312 where the rest of TxnStore 
methods are



standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/utils/MetaStoreServerUtils.java
Lines 1476 (patched)


I would put both of these in CompactionInfo.  If someone adds fields to 
CompactionInfo, they are unlikely to ever find these methods and so some info 
will be lost in the marshalling back and forth. 

Alternatively, could CompactionInfo be a subclass of CompactionInfoStruct?

Is this specific to a Java version?

Move this to the top and state that if this is set to false, we'll ignore 
the other SSL properties.



standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/ObjectStore.java
Line 332 (original), 398 (patched)


State that this is deprecated here and maybe increase the LOG to warn and 
note that this might be changed in next version of hive.

 Summary: Add option to schematool to drop Hive databases
 Key: HIVE-21034
 URL: https://issues.apache.org/jira/browse/HIVE-21034
 Project: Hive
  Issue Type: Improvement
Reporter: Daniel Voros
Assignee: Daniel Voros


An option to remove all Hive managed data could be a useful addition to 
{{schematool}}.

I propose to introduce a new flag {{-dropAllDatabases}} that would *drop all 
databases with CASCADE* to remove all data of managed tables.
