What doesn't meet your expectations?

NullPointException when readHadoopXml。

error info: java.lang.NullPointerException at org.apache.paimon.utils .HadoopUtils.readHadoopXml(HadoopUtils.java:228) at org.apache.paimon.utils .HadoopUtils.addHadoopconfIfFound(HadoopUtils .java:175) ....

becasuse hdfs-site.xml like this:

<property>
  <name>xxxx</name>
</property>

Anything else?

i have already got down it by modifing org.apache.paimon.utils.readHadoopXml() . it is very easy.

Are you willing to submit a PR?

please assign it to me . My solution is to add some non-empty checks. I have verified it in my company's internal version.
