------------------------------------
Summary: Import throws error message
"org.apache.thrift.protocol.TProtocolException: Required field 'filesAdded' is
unset!"
Key: HIVE-10727
URL: https://issues.apache.org/jira/browse/HIVE-10727
Project: Hive
Issue Type: Bug
Reporter: Balu Vellanki
Assignee: Sushanth Sowmyan
Here are the steps to reproduce. Please setup two hive warehouses with
hive.metastore.event.listeners set to
org.apache.hive.hcatalog.listener.DbNotificationListener. On warehouse 1,
please do the following as user hive.
{code}
## create table
CREATE TABLE page_view4(viewTime INT, userid BIGINT,
page_url STRING, referrer_url STRING,
ip STRING COMMENT 'IP Address of the User')
COMMENT 'This is the page view table'
PARTITIONED BY(dt STRING, country STRING)
STORED AS SEQUENCEFILE;
## Add partitions
alter table page_view4 add partition (dt="1", country="usa");
alter table page_view4 add partition (dt="2", country="india");
insert into table page_view4 PARTITION (dt="1", country="usa") VALUES (1, 1,
"url1", "referurl1", "ip1");
## Export table
export table page_view4 to '/tmp/export4' for replication('foo');
{code}
'/tmp/export4' is created with owner as hive and group hdfs. The
'/apps/hive/warehouse/page_view4/' is created with owner hive and group users.
Copy the exported data in '/tmp/export4' to hdfs in warehouse 2. The data is
still owned by hive and belongs to group hdfs. Please change the group for dir
'/tmp/export4' to users.
{code}
bash# su - hdfs
hdfs : bash# hadoop fs -chown -R hive:users /tmp/export4
{code}
As user hive, do the following
{code}
hive> import table page_view4 from '/tmp/export4' ;
Copying data from hdfs://node-4.example.com:8020/tmp/export4/dt=1/country=usa
....
Loading data to table default.page_view4 partition (country=usa, dt=1)
Failed with exception org.apache.hadoop.hive.ql.metadata.HiveException:
org.apache.thrift.protocol.TProtocolException: Required field 'filesAdded' is
unset! Struct:InsertEventRequestData(filesAdded:null)
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.MoveTask
{code}
The import failed. Attaching the logs from /tmp/hive/hive.log for further
debugging.
