Error exporting data from Google Cloud Bigtable

While going through the Google docs, I'm getting the below stack trace on the final export command (executed from the master instance with appropriate env variables set).

${HADOOP_HOME}/bin/hadoop jar ${HADOOP_BIGTABLE_JAR} export-table -libjars ${HADOOP_BIGTABLE_JAR} <table-name> <gs://bucket>

Here's my ENV var set up in case it's helpful:

export HBASE_HOME=/home/hadoop/hbase-install
export HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath`
export HADOOP_HOME=/home/hadoop/hadoop-install

export HADOOP_CLIENT_OPTS="-Xbootclasspath/p:${HBASE_HOME}/lib/bigtable/alpn-boot-7.1.3.v20150130.jar"
export HADOOP_BIGTABLE_JAR=${HBASE_HOME}/lib/bigtable/bigtable-hbase-mapreduce-0.2.2-shaded.jar
export HADOOP_HBASE_JAR=${HBASE_HOME}/lib/hbase-server-1.1.2.jar

Also, when I try to run hbase shell and then list tables it just hangs and doesn't fetch me the list of tables. This is what happens:

~$ hbase shell

I've tried:

  • Double checking ALPN and ENV variables are appropriately set
  • Double checking hbase-site.xml and hbase-env.sh to make sure nothing looks wrong.

I also even tried connecting to my cluster (like I was previously able to following these directions) from ANOTHER gcloud instance, but it seems like I can't seem to get that to work now either...(it also hangs)

Any ideas with what I'm doing wrong? Looks like an access issue - how do I fix it?

Thanks!

We are going to update the page to use Dataproc. In the mean time, you might try adding the netty-tcnactive jar. <groupId>io.netty</groupId> <artifactId>netty-tcnative</artifactId> <version>1.1.33.Fork7</version> to your classpath. – Les Vogel - Google DevRel
Thanks for the response @LesVogel-GoogleDevRel, but I still can't seem to access my cluster from the hbase shell. I downloaded the jar you specified and set it as part of my CLASSPATH (export CLASSPATH=/path/to/jar/netty-tcnative-1.1.33.Fork7.jar) and reran the shell. Still seems to hang. Did I do it wrong? Also, more importantly, any pointers on how to fix my first issue (exporting data from the table, rather than just accessing it from hbase shell). Thanks in advance! – Kamran
A colleague mentioned that this doesn't appear to be a Bigtable issue, but a GCS one. com.google.cloud.hadoop.gcsio.GoogleCloudStorageImpl.getBucket(GoogleCloudStorageImpl.java:1599) We've asked someone on that team to see if they can give some advise. – Les Vogel - Google DevRel
What version of the JDK are you using? – Les Vogel - Google DevRel
@LesVogel-GoogleDevRel: myuser@bigtable-instance-m:~$ java -version java version "1.7.0_95" OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-1~deb7u1) OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode) – Kamran

  1. You can spin up a Dataproc cluster w/ Bigtable enabled following these instructions.

  2. ssh to the master by ./cluster.sh ssh

  3. hbase shell to verify that all is in order.

  4. hadoop jar ${HADOOP_BIGTABLE_JAR} export-table -libjars ${HADOOP_BIGTABLE_JAR} <table-name> gs://<bucket>/some-folder

  5. gsutil ls gs://<bucket>/some-folder/** and see if _SUCCESS exists. If so, the remaining files are your data.

  6. exit from your cluster master

  7. ./cluster.sh delete to get rid of the cluster, if you no longer require it.

You ran into a problem with the weekly java runtime update, that has been corrected.
