Hi all,
I am using cdh5.11.1-release,the compilation command is provided in the
documentation(./buildall.sh -notests -so),but there is no command similar to
'make install'.In the current document compiled, the directory structure is too
much and do not need too many files. Could you provide
Hi Tim，
Is there a plan for this work? Could you provide a manual copy of the
example?Thanks.

Hi all,
When I used the command "./bin/start-impala-cluster.py" to start the
impala cluster, it will report the following error：

Hi Tim,
I found it from ./bin/create-test-configuration.sh that generating
./fe/src/test/resources configurations, and HADOOP_CONFIG_DIR variable also
points to this directory. But I change this variable is not take effect. Is
this a hard code?
question.

Hi all,
t1 table：3000 data
t2 table: 0 data, the table structure is the same as t1
using "insert into table t2 select * from t2;" will cause a timeout error.
Why ?
Hi all,
Is there any way to load data from hdfs to parquet table not via external
table or inner table？

Hi all,
In addition to "show tables" command, is there any other ways to show all
the tables in impala ?
I need a way to handle collection of all tables through SQL, but "show
tables" can not be combined with SQL.
Hi Dimitris,
What you mean is to query the database that stores the impala metadata ?
hive(mysql,pg,derby and so on) ?

Hi all,
How does impala interact data with other relational databases? Sqoop's
functionality is not perfect, and in impala, each insert has 100ms query plan
overhead. Are there any other easy ways to interact ？

Could you give me a impala driver source code connection?

Textfile and parquet,the two format both cause data confusion.

Why is the second step performed in hive, not impala?
