UnsupportedOperationException 在 IoTDB 中的 Compaction Merge 中发生，当 TsFile 存储在 HDFS 中时
UnsupportedOperationException occurred in Compaction Merge in IoTDB when TsFile storage in HDFS
我尝试将 TSFiles 本地化到 HDFS，配置如下：
tsfile_storage_fs=HDFS
core_site_path=/home/hadoop-2.7.7/etc/hadoop/core-site.xml
hdfs_site_path=/home/hadoop-2.7.7/etc/hadoop/hdfs-site.xml
hdfs_ip=IP
hdfs_port=port
异常是：

IoTDB 的压缩还没有适应 HDFS 中的存储。使用 HDFS 时，请通过设置 compaction_strategy=NO_COMPACTION 和 enable_unseq_compaction=false 关闭压缩。
