hi josh :
I met another two problems when i 'copy ' a table to another with
spark. The trouble should be decribed as "some null and empty values when
copied from another table "
The main code is as follows:
val sqlContext = new SQLContext(sc)
val pred = s"mmsi like '0%'"
val df = sqlContext.phoenixTableAsDataFrame("ais_mmsi",
Array("MMSI","TIME","C1.RID","C3.NAV_STATUS","C2.ROT....(total 13
columns)"),predicate = Some(pred),conf = configuration)
df.saveToPhoenix("ais_area_test3",conf = configuration).
when it finished. I check the table 'ais_area_test3', all the rid
seems to be empty,and some of other columns to be null. I really do not know
what happened.
And if i use phoenixTableAsDataFrame without any predicate . It
will cause another exception "
org.apache.phoenix.schema.StaleRegionBoundaryCacheException: ERROR 1108
(XCL08): Cache of region boundaries are out of date." I have search the
mailing list and googled it ,there is nothing help to me.
Here is code to generate the two tables(both 13 columns and 3 cfs,
the diffrent should be the primary key,and one column):
create table ais_area_test3 (
rid varchar,
time INTEGER(10) not null,
mmsi varchar(9),
c3.nav_status INTEGER(2),.......etc.
create table ais_mmsi (
mmsi varchar(9) not null,
time INTEGER(10) not null,
c1.rid varchar(10),
c3.nav_status INTEGER(2),......etc.
Yours very sincerely

[Sent this same message from another account, apologies if anyone gets a
double-post]
Thanks for the update. I hadn’t even seen the ‘SPARK_DIST_CLASSPATH’ setting
until just now, but I suspect for CDH that might be the only way to do it.
The reason for the class path errors you see is that the ‘client’ JAR on its
own ships a few extra dependencies (i.e. com.fasterxml.jackson) which are
incompatible with newer versions of Spark. The ‘client-spark’ JAR attempts to
remove those dependencies which would conflict with Spark, although a more
elegant solution will likely come with PHOENIX-2535
(https://issues.apache.org/jira/browse/PHOENIX-2535)
Re: speed, the spark integration should be just about as fast as the MapReduce
and Pig integration. At the 3T level, your likely bottleneck is disk IO just to
load the data in, although network IO is also a possibility here as well.
Assuming you have a sufficient number of Spark workers with enough RAM
allocated, once the data is loaded into Spark initially, operations on that
dataset should proceed much faster, as much of the data will be available in
RAM vs disk.
Best of luck,
Josh

Yes ,it is still the same 'No suitable driver' exception.
And my boss may solve the problem. the method is amazing but it
did succeed.
he add the "export
SPARK_DIST_CLASSPATH=$SPARK_DIST_CLASSPATH:/opt/cloudera/parcels/CLABS_PHOENIX/lib/phoenix/phoenix-1.2.0-client.jar"
in
spark-env.sh ,and restart the spark . And later ,everythig seems good. What
he add is the "phoenix-1.2.0-client.jar" which cause the exception
"java.lang.NoSuchMethodError:
com.fasterxml.jackson.databind.Module$SetupContext.setClassIntrospector" 。 It
is incredible. I really appreciate what you have done for me . If you
could tell me why it happens, i will be more happy.
Besides ,this afternoon i met anothor problem. I have made a
table which include 13 columns, such as (A.B.C.....) and the primary key is
(A,B), When i import all the data to this table ,i delete the original data.
But now i want to get another table ,which should inculde the same 13
columns ,but the diffrent primary key which should be (B,C). The data is
big ,about 3T . Could you tell me how to do it fastly. I have tried to do
this by spark, but it seems not fast.
Best wishes for you!

Hi,
Is it still the same 'No suitable driver' exception, or is it something else?
Have you tried using the 'yarn-cluster' mode? I've had success with that
personally, although I don't have any experience on the CDH stack.

I try to give you more informations, we have 11 nodes,3 zks,2

We use the CDH5.5 with spark1.5. our phoenix version is

I built the spark-client jar in the following steps
1.download the base code in

2. path the PHOENIX-2503.patch manualy
3 build
it is amazing that it did work in local ,but not in yarn-client

Hi,
The error "java.sql.SQLException: No suitable driver found..." is typically
thrown when the worker nodes can't find Phoenix on the class path.
I'm not certain that passing those values using '--conf' actually works or not
with Spark. I tend to set them in my 'spark-defaults.conf' in the Spark
configuration folder. I think restarting the master and workers may be required
as well.

Hi,
This issue is fixed with the following patch, and using the resulting
'client-spark' JAR after compilation:
https://issues.apache.org/jira/browse/PHOENIX-2503
As an alternative, you may have some luck also including updated
com.fasterxml.jackson jackson-databind JARs in your app that are in sync with
Spark's versions. Unfortunately the client JAR right now is shipping fasterxml
jars that conflict with the Spark runtime.
Another user has also had success by bundling their own Phoenix dependencies,
if you want to try that out instead:

Maybe I got the resoon ,the Phoenix 4.5.2 on CDH 5.5.x is build with spark 1.4
,and cdh5.5`defalut spark version is 1.5.
So how could I do? To rebuild a phoenix 4.5.2 version with spark 1.5 Or
change the cdh spark to 1.4. Apreantly these are difficult for me . Could
someone help me ? Thank you vey much.
