Syntax error while running the query in Hue-impala editor

 

Tutorial Exercise 2

 

Error while running the following query.

 

CREATE EXTERNAL TABLE intermediate_access_logs (
    ip STRING,
    date STRING,
    method STRING,
    url STRING,
    http_version STRING,
    code1 STRING,
    code2 STRING,
    dash STRING,
    user_agent STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
    'input.regex' = '([^ ]*) - - \\[([^\\]]*)\\] "([^\ ]*) ([^\ ]*) ([^\ ]*)" (\\d*) (\\d*) "([^"]*)" "([^"]*)"',
    'output.format.string' = "%1$$s %2$$s %3$$s %4$$s %5$$s %6$$s %7$$s %8$$s %9$$s")
LOCATION '/user/hive/warehouse/original_access_logs';

CREATE EXTERNAL TABLE tokenized_access_logs (
    ip STRING,
    date STRING,
    method STRING,
    url STRING,
    http_version STRING,
    code1 STRING,
    code2 STRING,
    dash STRING,
    user_agent STRING)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ','
LOCATION '/user/hive/warehouse/tokenized_access_logs';

ADD JAR /usr/lib/hive/lib/hive-contrib.jar;

INSERT OVERWRITE TABLE tokenized_access_logs SELECT * FROM intermediate_access_logs;

 

AnalysisException: Syntax error in line 11: ROW FORMAT SERDE 'org.apache.hadoop.hiv... ^ Encountered: IDENTIFIER Expected: DELIMITED CAUSED BY: Exception: Syntax error.

 

Any ideas to resolve the syntax error.

Re: Syntax error while running the query in Hue-impala editor

Use Hive Query Editor. It should work fine.

Re: Syntax error while running the query in Hue-impala editor

I have experienced the same issue when tried to pass the cloudera tutorials.

By the way, I used the Live VM that cloudera provides and I suppose that tutorials (http://www.cloudera.com/developers/get-started-with-hadoop-tutorial/exercise-2.html) were tested using the same environments.

 

It would be nice if somebody will explain the root cause and also provide a workaround.

Thank you in advance

Re: Syntax error while running the query in Hue-impala editor

As the previous reply said, you need to use the Hive Query Editor. The
error shows up if you use the Impala Query Editor because you're using a
library written for Hive.

Re: Syntax error while running the query in Hue-impala editor

Ok, if I select "Query Editors->Hive" and run the queries from that editor
it looks much better. I think the problem is that your assumption is that
everybody who starts this tutorial have some basic level of familiarity
with the tools. I believe that newbies like me will fall into this trap
unless you add a little bit more context or screenshots to this great
tutorial.

Thanks and kudos.

Re: Syntax error while running the query in Hue-impala editor

I was able to create the table with Impala in Hue using this syntax:

 

CREATE EXTERNAL TABLE intermediate_access_logs (
    ip STRING,
    `date` STRING,
    method STRING,
    url STRING,
    http_version STRING,
    code1 STRING,
    code2 STRING,
    dash STRING,
    user_agent STRING)
WITH SERDEPROPERTIES (
    'input.regex' = '([^ ]*) - - \\[([^\\]]*)\\] "([^\ ]*) ([^\ ]*) ([^\ ]*)" (\\d*) (\\d*) "([^"]*)" "([^"]*)"',
    'output.format.string' = "%1$$s %2$$s %3$$s %4$$s %5$$s %6$$s %7$$s %8$$s %9$$s")
LOCATION '/user/hive/warehouse/original_access_logs';

 

I was using the backquote (backward apostrophe) ` on line 3

Also I have removed the row format clause since it is not needed in Impala (check the doc: https://www.cloudera.com/documentation/enterprise/5-5-x/topics/impala_create_table.html#create_table).

We should use Hive Query Editor since some of the Examples syntax is not compatible with Impala and the tables are not created correctly.

 

i.e. https://community.cloudera.com/t5/Hadoop-101-Training-Quickstart/Unable-to-execute-add-jar-command-a...

Re: Syntax error while running the query in Hue-impala editor

This is pretty well laided out in the documantion...need to stop and read though it though.

Now you can build a table in Hive and query the data via Impala and Hue. You'll build this table in 2 steps. First, you'll take advantage of Hive's flexible SerDes (serializers / deserializers) to parse the logs into individual fields using a regular expression. Second, you'll transfer the data from this intermediate table to one that does not require any special SerDe. Once the data is in this table, you can query it much faster and more interactively using Impala.

We'll use the Hive Query Editor app in Hue to execute the following queries:
