> In TSServiceImpl#setMultiTimeSeriesPlan, the input create time series plan may not have any tag or attribute, thus createTimeSeriesPlan#getTags and createTimeSeriesPlan#getAttributes could return null. See:
> {code:java}
>   private void setMultiTimeSeriesPlan(
>       CreateMultiTimeSeriesPlan multiPlan, CreateTimeSeriesPlan createTimeSeriesPlan) {
>     PartialPath path = createTimeSeriesPlan.getPath();
>     TSDataType type = createTimeSeriesPlan.getDataType();
>     TSEncoding encoding = createTimeSeriesPlan.getEncoding();
>     CompressionType compressor = createTimeSeriesPlan.getCompressor();
>     Map<String, String> tags = createTimeSeriesPlan.getTags();
>     Map<String, String> attributes = createTimeSeriesPlan.getAttributes();
>     String alias = createTimeSeriesPlan.getAlias();
>     multiPlan.getPaths().add(path);
>     multiPlan.getDataTypes().add(type);
>     multiPlan.getEncodings().add(encoding);
>     multiPlan.getCompressors().add(compressor);
>     multiPlan.getTags().add(tags); // tags could be null !!!
>     multiPlan.getAttributes().add(attributes); // attributes could be null !!!
>     multiPlan.getAlias().add(alias);
>   }
> {code}
> The serialization of CreateMultiTimeSeriesPlan calls ReadWriteIOUtils#write(List<Map<String, String>>, ByteBuffer), and for each map in the list, ReadWriteIOUtils#write(Map<String, String>, DataOutputStream) is called. 
> However,  ReadWriteIOUtils#write(Map<String, String>, DataOutputStream) throws NPE when the input map is null.
