I've only got to step 1, sstable2json raises this exception when run with the
two problematic data files:
Exception in thread "main" java.io.UTFDataFormatException: malformed input
around byte 48
at java.io.DataInputStream.readUTF(DataInputStream.java:617)
at java.io.RandomAccessFile.readUTF(RandomAccessFile.java:887)

I tried to run it with another data file and it outputs its contents without
problems, so I suppose that those data files are corrupted, and I should
recreate the whole data store...
Thanks
