I am using CDH 5.9, while executing following hive query it is throwing error. Any idea about the issue?
For normal select query its working but for complex query it results failure.

Thanks.
Please check your data size as your job needs more space for logs but the jvm are less please scale your cluster or use specific query as you are using -
select * from table where dt='22-01-2017' and field like '%xyz%' limit 10
, as '%xyz%' will check whole data better to use specific requirement.
Else drop your table and create a new partitioned table with date as a partition column.
I am running several scripts and I keep getting this same error. All of them are multi tables join with the same condition.
Data is stored as parquet.

My data consists of about 20M records. When I try to join the tables with one column (end_user_id), I get the same error.
The join columns are the same data type. A join B as a subquery and then join C can solve this issue .
We have many SQL queries with multi-table join statements with the same condition, but only a few SQL scripts encounter these errors.
Make sure matching column data types should be same for all the tables
I'm trying to use ACID transactions in Hive but I have a problem when the data are added with Spark.
First, I created a table with the following statement :
CREATE TABLE testdb.test(id string, col1 string)
CLUSTERED BY (id) INTO 4 BUCKETS
STORED AS ORC TBLPROPERTIES('transactional'='true');
Then I added data with those queries :
INSERT INTO testdb.test VALUES("1", "A");
INSERT INTO testdb.test VALUES("2", "B");
INSERT INTO testdb.test VALUES("3", "C");
And I've been able to delete rows with this query :
DELETE FROM testdb.test WHERE id="1";
All that worked perfectly, but a problem occurs when I try to delete rows that were added with Spark.
What I do in Spark (iPython) :
hc = HiveContext(sc)
data = sc.parallelize([["1", "A"], ["2", "B"], ["3", "C"]])
data_df = hc.createDataFrame(data)
data_df.registerTempTable(data_df)
hc.sql("INSERT INTO testdb.test SELECT * FROM data_df");
Then, when I come back to Hive, I'm able to run a SELECT query on this the "test" table.
However, when I try to run the exact same DELETE query as before, I have the following error (it happens after the reduce phase) :
Error: java.lang.RuntimeException: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row (tag=0) {"key":{"reducesinkkey0":{"transactionid":0,"bucketid":-1,"rowid":0}},"value":null}

Thanks !
Use the Spark HiveAcid Datasource - http://github.com/qubole/spark-acid
val df = spark.read.format("HiveAcid").option("table", "testdb.test").load()
df.collect()
Spark needs to run with HMS 3.1.1 so that the underlying datasource can take necessary locks etc.
The directory structure, file formats are different for a Hive ACID table compared with a normal table. CRUD needs to happen from Hive.
With respect to Spark, normal table reads are not compatible with Hive ACID table reads. We could not use the native Spark apis to read the table.
Also, currently there is no support for updates, deletes, inserts in Spark
As for reading the data, one could use the connector - http://github.com/qubole/spark-acid
I had the same issue running from hue, but after I set these parameters from hive cli, it started working:
set hive.support.concurrency=true
set hive.enforce.bucketing=true
set hive.exec.dynamic.partition.mode=nonstrict;
set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DBTxnManager;
set hive.compactor.initiator.on=true;
I have an external table in hive that is stored on my hadoop cluster and I want to move its contents into an external table that is stored on Amazon s3.
So I created an s3 backed table like so:
CREATE EXTERNAL TABLE IF NOT EXISTS export.export_table
like table_to_be_exported
ROW FORMAT SERDE ...
with SERDEPROPERTIES ('fieldDelimiter'='|')
STORED AS TEXTFILE
LOCATION 's3a://bucket/folder';
Then I run: INSERT INTO export.export_table SELECT * FROM table_to_be_exported
It outputs the following

I have s3a key and secret set in my hadoop core-site.xml and am able to do reads and writes from s3 using hadoop directly hdfs dfs -ls s3a://.
Any guesses as to what I could do to get this to work?
Try using s3 instead of s3a, my guess is that s3a is not supported yet in EMR's Hive distribution.
I tried to run simple hive query through Datastax Enterprise, but it always fails with timeout (on small data set or even empty tables). I've got 4 nodes of m1.large on AWS (2x Cassandra & 2x Analytics). See below:
cqlsh:intracker> select count(*) from event_tracks_by_browser_date LIMIT 100000;
count

Then with hive:
