Hi Indu Nair,
Sorry for delayed response. Looking for your log the most important error I could see is:
"Request to create analyzer of unknown type:
SAP.TextAnalysis.DocumentAnalysis.FormatConversion.FormatConversionAnalyzer"
Please share your statement to create the index and also what you plan to index.
HANA can handle and process PDF, DOC files with some commands but it doesn't seems to be your case.
