hdfsBuilderConnect error while using tfserving load model from hdfs - tensorflow

Question

there is my environment info:
TensorFlow Serving version 1.14
os mac10.15.7
i want to load modle from hdfs by using tfserving.
when i build a tensorflow-serving:hadoop docker image,like this:
FROM tensorflow/serving:2.2.0
RUN apt update && apt install -y openjdk-8-jre
RUN mkdir /opt/hadoop-2.8.2
COPY /hadoop-2.8.2 /opt/hadoop-2.8.2
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64
ENV HADOOP_HDFS_HOME /opt/hadoop-2.8.2
ENV HADOOP_HOME /opt/hadoop-2.8.2
ENV LD_LIBRARY_PATH
${LD_LIBRARY_PATH}:${JAVA_HOME}/jre/lib/amd64/server
# ENV PATH $PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
RUN echo '#!/bin/bash \n\n\
CLASSPATH=(${HADOOP_HDFS_HOME}/bin/hadoop classpath --glob)
tensorflow_model_server --port=8500 --rest_api_port=9000 \
--model_name=${MODEL_NAME} --
model_base_path=${MODEL_BASE_PATH}/${MODEL_NAME} \
"#"' > /usr/bin/tf_serving_entrypoint.sh \
&& chmod +x /usr/bin/tf_serving_entrypoint.sh
EXPOSE 8500
EXPOSE 9000
ENTRYPOINT ["/usr/bin/tf_serving_entrypoint.sh"]
and then run :
docker run -p 9001:9000 --name tensorflow-serving-11 -e MODEL_NAME=tfrest -e MODEL_BASE_PATH=hdfs://ip:port/user/cess2_test/workspace/cess/models -t tensorflow_serving:1.14-hadoop-2.8.2
i met this problem. ps:i have already modify hadoop config in hadoop-2.8.2
hdfsBuilderConnect(forceNewInstance=0, nn=ip:port, port=0, kerbTicketCachePath=(NULL), userName=(NULL))
error:(unable to get stack trace for java.lang.NoClassDefFoundError exception: ExceptionUtils::getStackTrace error.)
is there any suggestions how to solve this problem?
thanks

Answer 1

i solved this problem by adding hadoop absolute path to classpath.
